D'oh you did say 4117vesa. so yes your whites are ffff as well you know.

This makes me wonder about shareing code between colorforthers. We are
branching the ( was block 30 with colors on it and in the new it is
26) colors and code for one system will not work for the other with
out re-writeing.

This could all be repaired if the 16bit systems used the 5:6:5 routine
to make the colors conguent between all systems.

This is a kernel routine and makes the 32bit color patterns in
old30/new26 block work in systems that use 16bit color information.

This issue won't come to a head until we begin really sharing code by
upload/download to the colorforth systems rather the re-writes.
