[Coco] colors

[Wayne Campbell]

I have been looking up all I can find about the CoCo3's 64 colors and the
16-color palette. I am finding some information to be incorrect, or at
least it seems to be incorrect. In addition, I find that the 64 colors as
they appear in composite mode make more sense than the colors as they
appear in RGB mode. From what I have read, it seems to me that this is more
due to the RBG side of things is not properly setting the colors. perhaps a
bit-shift would correct this? I don't know what it would take.

As far as the 16-color palette is concerned, the Rainbow Guide to OS-9 L2
says the first 8 registers are used for background and the last 8 are used
for foreground. This is not necessarily true, or VCC has a issue with the
colors (one or the other). As an example, if I set register 0 to 56 (light
gray) and register 8 to white, and I set a overlay window to use register 8
as background, I get light gray for the background color. According to the
book, I should see white as the background since I selected register 8 as
the register to use for background. Changing the register so 0 is white
(63) and 8 is light gray, the background becomes white. However, where I
have used REVON to change the characters to white fore and black back, I
get light gray for the foreground color instead of white.

Is there anyone on this list that understands the color registers enough to
help me make the colors work the way I want them to? I am just getting more
and more confused.
