Know the Color Wheel Primary Color
Introduction to Color/Hue Theory With Marlene Oaks Color affects us psychologically in nature, clothing, quilts, art and in decorating. The color choices we make create varying responses. Being able to use colors consciously and harmoniously can help us create spectacular results. Know the Color Wheel Primary color Primary color Primary color The color wheel is the basic tool for combining colors. The first circular color diagram was designed by Sir Isaac Newton in 1666. Primary, Secondary and Tertiary Colors Color theory in regards to light says that all colors are within white light—think prism, and black is devoid of color. In pigment theory, white is the absence of color & black contains all colors. We will be discussing pigment theory here. The primary colors are red, yellow and blue and most other colors can be made by various combinations of them along with the neutrals. The three secondary colors (green, orange and purple) are created by mixing two primary colors. Another six tertiary colors are created by mixing primary and secondary colors adjacent to each other. The above illustration shows the color circle with the primary, secondary and tertiary colors. 1 Warm and cool colors The color circle can be divided into warm and cool colors. Warm colors are energizing and appear to come forward. Cool colors give an impression of calm, and appear to recede. White, black and gray are considered to be neutral.

Several Color Appearance Phenomena in Color Reproduction
2nd International Conference on Electronic & Mechanical Engineering and Information Technology (EMEIT-2012) Several Color Appearance Phenomena in Color Reproduction Qin-ling Dai1,a, Xiao-zhou Li2*,b, Ai Xu2 1 School of Materials Engineering (Southwest Forestry University), Kunming, China 650224 2 Key Laboratory of Pulp & Paper Science and Technology (Shandong Polytechnic University), Ministry of Education, Ji’nan, China, 250353 [email protected], bcorresponding author: [email protected] Keywords: color reproduction, color appearance, color appearance phenomena Abstract. Color perceived performance was influenced by various color appearance phenomena caused by varying viewing conditions in color reproduction process. It is necessary to do some research on the color appearance phenomena to represent the color appearance models qualitatively and quantitatively and accurate color reproduction easily. Only the phenomena were studied thoroughly, could the color transmission and reproduction be well performed. The color appearance and common color appearance phenomena of color reproduction were analyzed in this paper. And the basic theory of color appearance in color reproduction was also studied. Introduction High fidelity digital printing plays an important role in high fidelity color transmission and reproduction and it is one of the most important techniques to perform high fidelity color reproduction. High fidelity digital printing helps to perform accurate color reproduction of the original which can’t be performed because of paper and ink in traditional printing process [1]. In color printing, the color difference caused by paper, ink and viewing conditions is various. The difference is not only colorimetric difference but also different color appearance phenomena. While the different color appearance phenomenon is the leading factor to influence the color vision perceived. -

Marianne Times Column
Portrait of the Artist: Marianne F. Buckley Curran By Theresa Brown “Portrait of the Artist” is a bi-weekly series introducing Hull Artists to the community by asking each artist to answer 10 questions that will give you a glimpse into their world. Marianne Buckley-Curran’s connection with Hull Artists goes back to its early founding years and the seasonal “Studio at the Beach” in the old MDC garage in the late ‘90s. Like many other Hull Artists, some of her earliest memories are of creative activities and a connection to an artistic family member. In her case a grandfather, who was a Lighthouse Keeper, sign painter, and artist, taught Marianne how to properly use an oil paint brush as a small child. Although art making continued to be an important part of Marianne’s life, practicality and natural athleticism led her to pursue a college degree and career in Physical Education. While taking a break from teaching to raise her family, Marianne was able to link her knowledge and love of art to a part time entrepreneurial venture as an artist agent. She arranged exhibition of works by other artists in area businesses as well as organized and operated local art shows. ****( my strategy was to learn the business of art while I was developing my own artistic vision ) Always surrounded by the artistry of others, Buckley-Curran began to question why she wasn’t exhibiting her own work and started entering her paintings in juried shows. Success in these shows encouraged her to refocus on making art and to study with local painter John Kilroy. -

Regionalism and Local Color Fiction in Nineteenth-Century Us Literature
Filologia y Lingiiistica XXVII(2): 141-153, 2001 THE POLITICS OF PLACE: REGIONALISM AND LOCAL COLOR FICTION IN NINETEENTH-CENTURY U.S. LITERATURE Kari Meyers Skredsvig RESUMEN Este articulo es el primero de una serie dedicada a las relaciones entre autoria femenina y la noci6n de lugar/espacio en la literatura estadounidense. Se presenta un panorama general a fin de contextualizar el regionalismo y el localismo como movimientos literarios y como subgdneros literarios en el desanollo de la literatura estadounidense del siglo diecinueve, mediante el andlisis de los contextos hist6ricos, sociales, politicos y literarios que inicialmente propiciaron estas dos tendencias literarias y posteriormente influyeron en su desapariciSn. Tambidn se examina el contenido cultural y aporte literario de estas etiquetas, asi como la posibilidad de intercambiarlas. ABSTRACT This is the first in a series of articles dealing with the interrelationships of female authorship and space/place in U.S. literature. This article provides an overview for contextualizing regionalism and local color both as literary movements and as literary subgenres in the development of nineteenth-century U.S. literature by exploring the historical, social, political, and literary environments which initially propitiated and later influenced the demise of these two literary tendencies. It also examines the cultural and literary import of these labels, as well as their possible interchangeability. Place and space are components of human reality at its most fundamental level. InThe Poetics of Space, Gaston Bachelard affirms that our home is "our first universe, a real cosmos in every sense of the word" (1994:4). We construct a personal identity not only for and within ourselves, but inevitably grounded in our context, at the same time that the environment constmcts us. -
Color Constancy and Contextual Effects on Color Appearance
Chapter 6 Color Constancy and Contextual Effects on Color Appearance Maria Olkkonen and Vebjørn Ekroll Abstract Color is a useful cue to object properties such as object identity and state (e.g., edibility), and color information supports important communicative functions. Although the perceived color of objects is related to their physical surface properties, this relationship is not straightforward. The ambiguity in perceived color arises because the light entering the eyes contains information about both surface reflectance and prevailing illumination. The challenge of color constancy is to estimate surface reflectance from this mixed signal. In addition to illumination, the spatial context of an object may also affect its color appearance. In this chapter, we discuss how viewing context affects color percepts. We highlight some important results from previous research, and move on to discuss what could help us make further progress in the field. Some promising avenues for future research include using individual differences to help in theory development, and integrating more naturalistic scenes and tasks along with model comparison into color constancy and color appearance research. Keywords Color perception • Color constancy • Color appearance • Context • Psychophysics • Individual differences 6.1 Introduction Color is a useful cue to object properties such as object identity and state (e.g., edibility), and color information supports important communicative functions [1].

Geography 222 – Color Theory in GIS Mike Pesses, Antelope Valley College
Geography 222 – Color Theory in GIS Mike Pesses, Antelope Valley College Introduction Color is a fundamental part of cartography. We have conventions that we learn early on in school; water should be blue, vegetation should be green. At the same time, we do not want to limit ourselves. While a magenta ocean may be a bit much, we can experiment with alternatives to convey a certain feeling for the map. Conventional light blue and tan world maps can feel a bit dull, whereas an “earthier” color scheme can get us thinking about exploration and piracy. A slight change in color can have major results. Color may seem like a simple enough concept, but its reproduction on paper, a television, or on a computer screen is an incredible science. To properly use color from a design standpoint, we must have at least a basic understanding of how it is produced. Color Systems Red, Green, Blue or RGB is the color system of televisions and computer screens. By simply mixing the proportions of red, green, and blue lights in screens, we can display a wealth of colors. We call this an additive system in that we add colors to make new ones. For example, if we mix red and green light, we get yellow. Mixing green and blue will produce cyan. Red and blue will make magenta. Red, green, and blue mixed together will produce white. Keep in mind that this is different from when you mixed paints in kindergarten. Mixing red, green, and blue paint will get you ‐1- Geog 222 – Color Theory in GIS, pg.
