Oh, so there are now. My bad.
I just checked and there is only 20 colors
Nice, though you have not tracked down all of them for I checked and there were 25 colors; it still ended up to count for the comp.
~And btw, the software I use for pixel art, though not the best, it does include a "magic pallete" that shows all the colors that I'm currently using within the full project. To be so kind, I took the liberty and imported your picture onto this software and it shows all the colors, 27 in total at first. When I looked at them some seemed to be almost the exact same.
Thanks! How did you find the stray colors?
Um... Yah, I just rechecked. There are 27 colors within it, and 28 within the preview, but the preview doesn't matter. Some of the colors are almost the same which may be a problem. I'd suggest that you quickly track down 'stray' colors and make them the same as their counterparts, then resubmit. As relevent to the current time you only have around three hours to do so before this great piece may not count.
Sorry for telling you this stuff if you didn't want to hear it, but I'm just looking out for you and other fellow pixel artists of this grand website. No hard feelings. :)
Thanks! But it doesn't have 27 colors it only has 18 colors
Pretty nice, but if that was for the dice challenge, that is too many colors. Max 20 while that is 27.
