Tutorial Post 7: Colors.

You can invoke color-chooser sub-menu to select the color of the cursor ('QCC') or of the background  ('QDB'):

You can choose one of the eight predefined colors by pressing one of the keys: '0', ... , '7'.

You can also 'fine tune' each component of the color  by pressing one of its two keys. For example, the red component is increased by pressing 'R' and it is decreased by pressing 'E' (next key left to 'R' on QWERTY keyboard).

If you want to reuse  some color that is already used in the model you can select some endpoint with this color and use the 'N' key. The 'N' key cyclically selects colors from the selected endpoints. (Sometimes it is hard to select a single endpoint if other endpoints are in the same place.)

Note that the color-chooser sub-menu is persistent. To leave it, you have to press one of the keys: 'Q', ESCAPE, ENTER.
