I've displayed your test image in Neochrome Master:sporniket wrote: ↑Thu Mar 17, 2022 9:56 pm @mrbombermillzy
Do you have a simple PI1 viewer, to display this test image ? TEST.zip
on the ste/twin shifter, you should see 16 colors, like this (forget the UI of deluxe paint ) :
test-reference-ste.png
on a regular ST, you should see only 8 colors :

However, I'm not sure how the program will decide to use the STe (or higher) palette on a Mega ST?
The blue hues in my post above (which you mention) reveal at least an STe palette match, if that's what you are looking for? (Also look at TS3v2.jpg for a digitally boosted red to prove STe palette availability in the output.) I have coded the program to output up to 16bpp, so this is a better way of showing enhanced palette colours. (Just need to unify the test displays and ditch the CRT).
