If you do not position the eyedropper directly on one of the two end tiles, the tile closest to the end is filled with the eyedropper color. Note that the cursor must be inside the interpolator. Use the Undo button to reverse the last interpolator action, which can be a smear, the filling of an end tile, or the activation of one of the warmth or lightness adjustment buttons. The HLS color model contains three scales that represent the ranges of hue, lightness, and saturation. Hue is color.
Saturation is the purity of the color, or how much the color is diluted by white.
The RGB color model contains three scales that represent the color ranges for red, green, and blue. Specify a color by indicating the intensity of color on each of the three scales. Each tile in the window displays a different color along with the color name. Use the scroll bar to display the entire list. Click MB1 on a tile to select a color.
