Less spacing between sub-forums on the forum home page, so that I can see all subforums without scrolling. And is there not a feature to show if something new has been posted in the subforum since the last visit?

I very often get a 'sessions mismatched' error, even though I never have to login again after that

Or this one:

You mean this?

Very nice! Making my own deck of cards has been a long standing dream which I've never acted upon, it's inspiring to see you bit the bullet and actually pixelled and printed a deck.

Selling a product is not easy, so I wish you a lot of good luck!

Oh yes, I understand its not beneficial to the quality of the palette at the extreme level, but I'd still be curious!

I'm very surprised that the Resurrect 32 is the lowest, it does not hold full black, so the distances could be much bigger if it were stretched to include that, right? Also, from glancing over it many colors do seem similar, but that might be just my eyes playing tricks.

By the way, an alternative for calculating distance would be to use DawnBringer's weighed formula, which is adjusted to brightness perception.

To quote a message he sent me:

Brightness is key! Brightness is the most dominant dimension and property of a color. That's why it's usually very helpful to add a brightness-weight into a colormatching procedure, especially if you're seeking perceptual correctness.

This is my own (current) formula for calculating preceptual brightness of a color, color distances and color matching.

brightness = math.sqrt((r*0.26)^2 + (g*0.55)^2 + (b*0.19)^2) * 1.5690256395005606

-- # Color Distance (hardcoded gammma correction of 2.0)

-- Returns Normalized result (0..255, 255 is the distance black to white)
-- Dawn3.0 weights = 0.26,0.55,0.19
--
function db.getColorDistance_weightNorm(r1,g1,b1,r2,g2,b2,rw,gw,bw)
 return ( (rw*rw*(r1-r2)*(r1-r2) + gw*gw*(g1-g2)*(g1-g2) + bw*bw*(b1-b2)*(b1-b2)) / (rw*rw + gw*gw + bw*bw) )^0.5
end

This stuff should also be in the DB toolbox for Grafx2

This sounds fun!
How will the marbles be raced?

Hmm this file broke, I used the lospec uploader. How come?

Try 2:

And once more using the forum uploader just in case:

Very nice work! I'd love to be able to read this score on every palette page.

Nice that you've experimented with different color spaces for distance.

Also, I'm curious now, what is the best spread palette? And would it be possible to generate the best possible palette(s) with the distances as close to the mean as possible?
