13 | Basics Windows and Editors Reference > Color Chooser Eyedropper The eyedropper tool lets you grab a color from anywhere on the computer screen, including other applications. Click the eyedropper button, then position the eyedropper cursor anywhere on your screen. Click again to grab the color. Using the sliders For precise color selection, you can use the color sliders. You can switch between RGB sliders (Red, Green, Blue) or HSV (Hue, Saturation, Value), depending on the color model you want. HSV In this color model, Hue corresponds to the pure colors of the rainbow, such as yellow, blue, and green. Saturation is the amount of white mixed with the hue to set the intensity of the color. Value is the amount of black mixed with the hue to make it darker. If the Value is 0 (zero), then the color is black, regardless of the values for Hue and Saturation. RGB This color model describes how red, green, and blue light combines at different intensities to produce different colors. Using RGB, you can select which value range you want. 0 to 1 Each component color has a value from 0 to 1. 0 to 255 Each component color has a value from 0 (zero intensity) to 255 (full intensity). This model is useful because it relates directly to how monitors emit light to create colors. However, it is often hard for people to figure out what the RGB values are for a specific color. A (alpha) slider With the A (alpha) slider, you can control the opacity or transparency of the color you select. Many Maya options already have an alpha or transparency control, but if it does not or you are calling the Color Selector from the command line, you can use this slider to control the alpha channel. ™ "Organize objects on display layers" on page 136 Blend box The Blend box creates a blend between colors so that you can select a new color from the blended gradient.
