Thomas Young postulated that the eye contains receptors that respond to three different primary sensations, or spectra of light. James Clerk Maxwell showed that all hues, and almost all colors, can be created from three primary colors such as red, green, and blue, if they are mixed in the right proportions. Goethe's Theory of Colours provided the first systematic study of the physiological effects of color (1810). His observations on the effect of opposed colors led him to a symmetric arrangement of his color wheel anticipating Ewald Hering's opponent color theory (1872). Gradient RGB/ CMY color wheel Seven-color and twelve-color color circles from 1708, attributed to Claude Boutet Wilhelm von Bezold's 1874 Farbentafel The psychophysical theory behind the color circle dates to the early color triangle of Thomas Young, whose work was later extended by James Clerk Maxwell and Hermann von Helmholtz.

Next, we have very small circles! These 2 inch circle outlines are great for smaller craft projects, or for creating polka dots!

A color wheel or color circle [1] is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc. With this fertile ground of traits and visions, we bring about important changes. Do you complete the list? For another option, these Carpet Area Sitting Stars are similar in design to the Editable Circle Template Sheets, bar the shape of course. They’re not only excellent for encouraging children to sit sensibly, but they can also be used as fun display pieces. After all, when a resource is editable, there’s no limit to the possibilities. Never clean the surface with glass cleaner. This product leaves particles that are not compatible with the adhesive. We recommend cleaning the surface with water or cleaning alcohol from the pharmacy.
We created 2 printable circle outlines for the smaller templates. You can choose from just a single circle per printable PDF file. Some sources use the terms color wheel and color circle interchangeably; [2] [3] however, one term or the other may be more prevalent in certain fields or certain versions as mentioned above. For instance, some reserve the term color wheel for mechanical rotating devices, such as color tops, filter wheels or the Newton disc. Others classify various color wheels as color disc, color chart, and color scale varieties. [4] History [ edit ] a b Schiffman, H.R. (1990) Sensation and perception: An integrated approach (3rd ed.).

A color wheel based on RGB (red, green, blue) additive primaries has cyan, magenta, and yellow secondaries. Alternatively, the same arrangement of colors around a circle can be described as based on cyan, magenta, and yellow subtractive primaries, with red, green, and blue being secondaries. Sometimes a RGV (red, green, violet) triad is used instead. In an additive color circle, the center is white or gray, indicating a mixture of different wavelengths of light (all wavelengths, or two complementary colors, for example). The HSL and HSV color spaces are simple geometric transformations of the RGB cube into cylindrical form. The outer top circle of the HSV cylinder – or the outer middle circle of the HSL cylinder – can be thought of as a color wheel. There is no authoritative way of labelling the colors in such a color wheel, but the six colors which fall at the corners of the RGB cube are given names in the X11 color list, and are named keywords in HTML.

The red colouration of the under-eye circle is caused by micro capillaries which are most frequently located in the innermost corners of the eye contour. The dilation of these vessels may be heredity, or related to the ageing process or even to external climatic conditions. The laser treatment solution used to eliminate red circles is the KTP® laser. The energy from this vascular laser stimulates the vessels and makes them retract then totally disappear. The results lasts for several years and can even be permanent when the laser is correctly configured and sessions are correctly performed by an experienced practicioner. Coloured Circle is for every individual and every organisation and company that strives for connection and cohesion.I have identified several types of coloured under eye circles and a laser treatment that is adapted to each of them:
