Thanks to Steelion in this
topic, I discovered two, maybe three rather interesting effects of setting color values to something higher than 7.
Values 8-15Setting the value of the foreground or background color to anything from 8 to 15, with the brightness value at Zero, appears to set it to the same colors of the "standard" values of 0-7, in the same order. However, the brightness value will effectively be
Nonzero. Although this may not seem very interesting at first, it also applies to background color, meaning that you can use this trick to
give the background a "bright" color, which is not possible using the standard values.Setting the foreground or background color to 8-15 and setting the brightness to Nonzero has unusual effects that appear to affect both colors, even if one of them is a "standard" value. I'm not sure of the specifics yet (although the colors appear to be constant, as opposed to the higher values I'll get to in a few seconds), and I will continue to research that later. Secondly:
Values higher than 15:Setting the foreground value to anything higher than 15 has an odd effect. At first, I thought the creature was cycling through several colors, almost always green and occaisonally gray. After a minute or two of careful examination, I realized that
the creature's color depended on the corresponding color of the tile it was standing on. Xenomorph has a more technical explanation in the topic I mentioned earlier.
Setting the background value has the same effect, but since almost all (if not all) walkable tiles have a black background, the creature's background will probably be black in all cases except on the unit list.
Note: setting the brightness value to anything other than 0 or 1 appears to act as 1. This is probably because it only checks for zero or nonzero numbers.
My to-do list:
- find the exact effect of setting a color to 8-15 and setting the brightness to nonzero
- check for effects of negative values
