The default palette

For applications with minimal color requirements, a default palette is provided that contains 16 colors. The following table gives the pixel-value-to-color mapping of the default palette.

Table 22. Pixel-value-to-color mapping for the default palette

Pixel value Color Pixel value Color
0 black 1 dark red
2 dark green 3 dark yellow
4 dark blue 5 dark magenta
6 dark cyan 7 light gray
8 gray 9 red
10 green 11 yellow
12 blue 13 magenta
14 cyan 15 white

All windows have the default palette selected unless the application has selected a different palette. Use of the default palette has some key advantages:

Some platforms, such as OS/2 and Windows, provide an operating system default palette containing some or all of these colors. On these platforms, the colors in the Common Graphics default palette use the same color intensities as the corresponding colors in the operating system default palette in order to minimize color resource allocation.

Tip:
The default palette is retrieved by evaluating CgIndexedPalette default.
