On the Colors tab in the dialog box of the ribbon command File | Properties 
, you can edit the color palette of the current document.
When you open a color list – for example, the color list for the font color – you see only a small selection of the up to 16 million colors available. This selection is called the color palette of the document.
You can modify this color palette at any time. You can add new colors and change colors that you have added. However, the first 24 colors in the palette are default colors that cannot be changed.
Important: Changes to the color palette are saved in the document. This means that you can create a separate color palette for each document.
Adding a color
To add a color to the palette of the current document, proceed as follows:
| 1. | Choose the command File | Properties and switch to the Colors tab. |
Tip: Alternatively, this color palette can be accessed via any button that contains a color list (for example, font color). To do so, select the entry Define color... in the color list (the last entry).
| 2. | Set the desired color. For more information, see "Working with the color controls" section below. |
| 3. | Click on the New button. |
| 4. | Give the new color whatever name you like and confirm with OK. |
| 5. | Exit the dialog box with OK. |
Presentations now adds the new color to the document's color palette. From now on, the color will be available in all dialog boxes where a color can be selected.
Changing a color
Note: You can only change colors that you have added. The first 24 colors in the color palette are default colors that cannot be changed.
To change a color, proceed as follows:
| 1. | Choose the command File | Properties and switch to the Colors tab. |
| Alternatively: You can also select the entry Define color... in any color list (for example, font color) to open this dialog box. |
| 2. | Select the color to be changed from the Color palette list. |
| 3. | Make the desired changes. For more information, see "Working with the color controls" section below. |
| 4. | Click on Change. |
The color has now been changed for the current document.
Renaming a color
You can change the name of self-defined colors at any time. To do so, open the color dialog, select a color from the dropdown list Color palette and click on the Rename button.
Working with the color controls
The controls in the above dialog box let you set colors in many ways. All these ways lead to the same result – just select your preferred method:
▪Using the color field and luminance slider
| The easiest way to set colors is to use the large color field and the luminance slider to its right. The color field presents all available hues in all available saturations, while the luminance slider next to it provides a means of varying the luminance. |
| To set a color, first click on the desired color in the large color field. Then click on the desired luminance in the luminance slider. |
▪Using the hue, saturation and luminance controls
| Alternatively, you can set colors with the controls labeled Hue, Sat (saturation) and Lum (luminance). Values between 0 and 240 are allowed. |
▪Using the Red, Green and Blue controls
| Colors can also be set via their red, green and blue components. The controls labeled Red, Green and Blue are provided for this purpose. Values between 0 and 255 are allowed. |
▪Typing the hex code for a color
| You can also specify a color by typing its hex code in the input field with the hash (pound) sign #. |
| Such hex codes are common in the HTML code of web pages, for example. The hex code consists of 3 two-digit hexadecimal values for the colors red, green and blue (RRGGBB). For example, 00FF00 represents pure green. |
