Hehe so cheesy. Nice interlace dithering here and there though. Of course a copy.

I think that Danny pic some Amiga AGA hires mode. Not 100% sure tho.
There are no ugly colours, only ugly combinations of colours.

That's what I thought also, since, Danny... PC... why? Lazur has a big amount of tallpixel pieces too.

Yeah well I did say 'like that' , not that it was done for/on the PC:)
If you insist on being pessimistic about your own abilities, consider also being pessimistic about the accuracy of that pessimistic judgement.

I've just been reading up on gamma,
And I realize the colors I gave are wrong for modern sRGB displays, since CPC is a linear RGB colorspace and sRGB is a nonlinear (gamma 2.2) colorspace.

The revised colors:


Something to keep in mind for any future posters to this thread -- check your gamma. Because most retro palettes
were drawn on a device with linear RGB, you'll need to gamma-correct the color values.

EDIT: the above is bullshit, I retract it. Nonlinear gamma is normal, so it is only a matter of correcting from the original gamma to the modern sRGB gamma ~2.2 (which is a three step process, first apply gamma (1/original_gamma), then apply gamma (~2.2)
NOTE: sRGB gamma isn't actually 2.2 (pc) or 1.8 (mac), it's a splicing together of two functions, one of which is linear (from 0..12 AFAIK) and one of which is exponential (gamma 2.5, for PCs)), which is commonly approximated by gamma 2.2.

More on gamma later, in a new thread.
