Colors and color palettes
Draw (like all LibreOffice components) uses color palettes for the representation of colors. You can
customize the color palette to suit your own needs by modifying colors in a palette, adding other
colors, or creating new color palettes.
Note
LibreOffice uses the RGB color model internally for printing in all of its software
modules. The CMYK controls are provided only to ease the input of color values
using CMYK notation.
Using colors
Two color dialogs are available where you can select, add, modify, edit, or delete colors. Go to
Tools > Options > LibreOffice > Colors (Figure 256) or Format > Area > Colors (Figure 257) on
the main menu bar to open these color dialogs. You can also right-click on a selected object and
choose Area in the context menu, then click on the Colors tab to open the Area dialog (Figure
257).
Each color value has a numeric value, which can be input directly as numbers. The color values for
the RGB color model (Red, Green, and Blue) can be any integer value between 0 and 255. The
color values for the CMYK color model (Cyan, Magenta, Yellow, and Black (K)) are percentages.
When selecting between the RGB and CMYK color models in both dialogs, the value boxes
automatically change to show RGB or CMYK.
When using CMYK values, the conversion to RGB values used in LibreOffice is made
automatically. Any modifications made to colors apply only to the active palette in your drawing
unless you save the modified color palette for future use.
