Power Area Density in Inverse Spectra
Power Area Density in Inverse Spectra Matthias Rang1 and Johannes Grebe-Ellis2 1Forschungsinstitut am Goetheanum, Dornach 2Bergische Universität Wuppertal Abstract In recent years, inverse spectra were investigated with imaging optics and a quanti- tative description with radiometric units was suggested (Rang 2015). It could be shown that inverse spectra complement each other additively to a constant intensity level. Since optical intensity in radiometric units is a power area density, it can be expected that energy densities of inverse spectra also fulfill an inversion equation and complement each other. In this contribution we report findings on a measure- ment of the power area density of inverse spectra for the near ultraviolet, visible and the infrared spectral range. They show the existence of corresponding spectral re- gions ultra-yellow (UY) and infra-cyan (IC) in the inverted spectrum and thereby present additional experimental evidence for equivalence of inverse spectra beyond the visible range. Introduction In his theory of colour, Goethe described the observation that inverse optical contrasts, viewed through a prism, lead to complementary spectral phenomena (Goethe 1970, Müller 2015).1 This observation has been variously addressed and linked to the questions of whether the inverted spectrum can be physically applied (Kirschmann 1917, 1924) and whether the complementarity of spectral phenomena can be generalized experimentally (Bjerke 1961). Particular attention has been given to the problem of inverting Newton's Experimentum crucis, designed to demonstrate the purity of selected spectral re- gions (Holtsmark 1970, Sällström 2010). The philosophical discussion on Goethes theory of colour has been rekindled since Olaf Müller published his comprehensive work on Goethe, Newton and the controversy about colour theory (Müller 2015). -

Color Mixing Ratios
Colour Mixing: Ratios Color Theory with Tracy Moreau Learn more at DecoArt’s Art For Everyone Learning Center www.tracymoreau.net Primary Colours In painting, the three primary colours are yellow, red, and blue. These colors cannot be created by mixing other colours. They are called primary because all other colours are derived from them. Mixing Primary Colours Creates Secondary Colours If you combine two primary colours you get a secondary colour. For example, red and blue make violet, yellow and red make orange, and blue and yellow make green. If you mix all of the primary colours together you get black. The Mixing Ratio for Primary Colours To get orange, you mix the primary colours red and yellow. The mixing ratio of these two colours determines which shade of orange you will get after mixing. For example, if you use more red than yellow you will get a reddish-orange. If you add more yellow than red you will get a yellowish-orange. Experiment with the shades you have to see what you can create. Try out different combinations and mixing ratios and keep a written record of your results so that you can mix the colours again for future paintings. www.tracymoreau.net Tertiary Colours By mixing a primary and a secondary colour or two secondary colours you get a tertiary colour. Tertiary colours such as blue-lilac, yellow-green, green-blue, orange-yellow, red-orange, and violet-red are all created by combining a primary and a secondary colour. The Mixing Ratios of Light and Dark Colours If you want to darken a colour, you only need to add a small amount of black or another dark colour. -
Absorption of Light Energy Light, Energy, and Electron Structure SCIENTIFIC
Absorption of Light Energy Light, Energy, and Electron Structure SCIENTIFIC Introduction Why does the color of a copper chloride solution appear blue? As the white light hits the paint, which colors does the solution absorb and which colors does it transmit? In this activity students will observe the basic principles of absorption spectroscopy based on absorbance and transmittance of visible light. Concepts • Spectroscopy • Visible light spectrum • Absorbance and transmittance • Quantized electron energy levels Background The visible light spectrum (380−750 nm) is the light we are able to see. This spectrum is often referred to as “ROY G BIV” as a mnemonic device for the order of colors it produces. Violet has the shortest wavelength (about 400 nm) and red has the longest wavelength (about 650–700 nm). Many common chemical solutions can be used as filters to demonstrate the principles of absorption and transmittance of visible light in the electromagnetic spectrum. For example, copper(II) chloride (blue), ammonium dichromate (orange), iron(III) chloride (yellow), and potassium permanganate (red) are all different colors because they absorb different wave- lengths of visible light. In this demonstration, students will observe the principles of absorption spectroscopy using a variety of different colored solutions. Food coloring will be substituted for the orange and yellow chemical solutions mentioned above. Rare earth metal solutions, erbium and praseodymium chloride, will be used to illustrate line absorption spectra.

Color Matters
Color Matters Color plays a vitally important role in the world in which we live. Color can sway thinking, change actions, and cause reactions. It can irritate or soothe your eyes, raise your blood pressure or suppress your appetite. When used in the right ways, color can even save on energy consumption. As a powerful form of communication, color is irreplaceable. Red means "stop" and green means "go." Traffic lights send this universal message. Likewise, the colors used for a product, web site, business card, or logo cause powerful reactions. Color Matters! Basic Color Theory Color theory encompasses a multitude of definitions, concepts and design applications. There are enough to fill several encyclopedias. However, there are basic categories of color theory. They are the color wheel and the color harmony. Color theories create a logical structure for color. For example, if we have an assortment of fruits and vegetables, we can organize them by color and place them on a circle that shows the colors in relation to each other. The Color Wheel A color wheel is traditional in the field of art. Sir Isaac Newton developed the first color wheel in 1666. Since then, scientists and artists have studied a number of variations of this concept. Different opinions of one format of color wheel over another sparks debate. In reality, any color wheel which is logically arranged has merit. 1 The definitions of colors are based on the color wheel. There are primary colors, secondary colors, and tertiary colors. Primary Colors: Red, yellow and blue o In traditional color theory, primary colors are the 3 colors that cannot be mixed or formed by any combination of other colors. -
