Chat May Use an Incorrect Background Color

SUMMARY

The Chat accessory included with Windows NT will only use solid colors for the background, even if the color displayed in the Colors dialog box is a dithered (non-solid) color. (To access the Color dialog box, choose Background Color from the Options menu.) Choosing a dithered color will cause Chat to display the solid component of the dithered color.

This behavior is by design. When a background color is selected, Chat performs a NearestColor match to find the nearest solid color that it represents. This is required to correctly match the text background (which cannot represent dithers).
