Title: Working with a specific high-color palette? (here's looking at you, 15/16-bit)
Post by: WM on November 15, 2015, 06:42:56 am

Okay, so I've been reading up on hardware restrictions on various systems lately and I want to try my hand at a Gameboy Color mockup.

The problem is that I'm a little uncertain how to go about finding/using correct colorspaces, or setting up my workflow for these colorspaces. Is there a copy-paste image of all colors for the occasionally-mentioned 15-bit rgb555 palette for this?

I'm looking at this

but there's 2x the colors there. Do some colors repeat? Is RGB presentation the only way to lay this out?

Thanks ahead of time!  :D

Surt made a handy tool (http://img.uninhabitant.com/colourcube.html) for this recently.

As far as working in a colourspace I have heard you can do that in promotion. Otherwise you'll just need to keep an eye on the RGB channels and make sure they're on the right values.

Gpick may be useful for sorting the palette into a different layout.

GrafX2 can also control colour space granularity. Right click "PAL" button and adjust "RGB Scale". It's in levels rather than bits, so just choose the relevant POT (32 in this case).

Thanks for the info, all of this helps a lot. Time to dig up GrafX2..

You can also use this color mode in Photoshop simply by having a posterize adjustment layer, above all your other layers, set to 32 levels (5 bits = 32 levels per channel).
