|  PP07S-1.2.2 You may like a certain color theme except for one or two colors. You can change an existing color theme (New!) and apply your changes to the entire presentation or to just a few slides. You can add other custom colors to your theme by using RGB (Red, Green, and Blue) or HSL (Hues, Saturation, and Luminosity) color modes. The RGB color mode is probably the most widely used of all the color modes. You can accomplish this by using sliders, dragging on a color-space, or entering a numeric value that corresponds to a specific color. Once you create this new color theme, you can add it to your collection of color themes so that you can make it available to any slide in the presentation. Change a Color in a Standard Color Theme

The Properties of Color |
|---|
Characteristic | Description |
|---|
Hue | The color itself; every color is identified by a number, determined by the number of colors available on your monitor. | Saturation | The intensity of the color. The higher the number, the more vivid the color. | Luminosity | The brightness of the color, or how close the color is to black or white. The larger the number, the lighter the color. | Red, Green, Blue | Primary colors of the visible light spectrum. RGB generates color using three 8-bit channels: 1 red, 1 green, and 1 blue. RGB is an additive color system, which means that color is added to a black background. The additive process mixes various amounts of red, green and blue light to produce other colors. |
