Searching for more Colours

AFTER THE COLOURS RUSH
This work is a collaboration between Simon Jonassen and Pere Serrat (me).
This began in the moment I first contacted Simon to ask some questions related to his ‘half-char’ shift demo.
This genius is also known as the mad guy from the c64 scene that likes to stretch the limits of the Coco II as well
This is going to be a series of posts in order to avoid a too big input.
Both of us have been in search of more colours on the Coco II/Dragon platforms for a LONG time, and various concepts have been tried and tested.
Simon cooked this idea after having taken some inspiration from the current c64 scene where they are doing the same kind of thing.
After Simon convinced me that this actually would and could work, the first step we took was based on the semi-graphic mode 24 that allows
for the eight standard colours plus black and two spaces, light green and dark green or light orange and dark orange depending on the palette you use.
This means that 11 colours can be mixed one with each other giving 121 possible combinations.
I made the first program to create these 121 combos on the screen, and despite the area for each combination not being very large,
you can see some colours blend to give a new colour, yet others don’t and simply show a stripped area.
I didn’t believe it until I saw the result on my Dragon screen!
These are the XRoar screenshots for both palettes.
Unfortunately XRoar emulates computer behaviour but not PAL behaviour … (the receiver end), so all stripped combos.
If we run this program on a real computer (CoCo2PAL – Dragon32-64) the result will be like this (bad) photo.
