How Can Light Be Mixed to Make New Colors
A page from the "Causes of Color" showroom...
What color do you get when y'all mix blue and yellow?
Principal colors and mixing of colors
If you mix ruddy, green, and blue light, y'all become white low-cal. Red, green, and blue (RGB) are referred to every bit the primary colors of light. Mixing the colors generates new colors, as shown on the color cycle or circle on the right. This is additive color. Every bit more colors are added, the result becomes lighter, heading towards white. RGB is used to generate color on a computer screen, a TV, and any colored electronic display device.
When you mix colors using paint, or through the press process, you are using the subtractive color method. The master colors of light are ruddy, green, and blue. If you subtract these from white y'all go cyan, magenta, and xanthous. Mixing the colors generates new colors as shown on the color wheel, or the circle on the correct. Mixing these iii primary colors generates black. Every bit you mix colors, they tend to get darker, catastrophe up as blackness. The CMYK color system (cyan, magenta, yellow, and black) is the colour system used for printing.
Experiment with this RGB color mixer to go a feel for the effect of mixing the 3 different additive chief colors. The exam box beside each slider shows the relative proportions of red, blueish and green on a scale from 1 to 255. The sliders themselves show the advent of the individual colors for your selected color. Find how the resulting color compares with pigment-based mixing – the effects are very different.
J.C. Le Blon discovered the main nature of red, yellow, and blue in pigment mixes. The above pictures (from effectually 1720) show the 2d and final plates in his four-stage printing method (using red, yellowish, blue, and blackness).
