Here is an update to my backsprite. I've been playing with the color palette to reduce any unnecessary colors.
For CAP pokemon there is no color limit to the sprites. On Shoddy, we can implement whatever we think looks good. However, all ingame Pokemon sprites have 16 colors or less (even though the DS can easily display a lot more). Therefore, if CAP spriters use way too many colors, it might not look consistent with other pokemon sprites.
Personally, I'm not obsessed with hitting 16 colors on the nose. However, I don't want to go overboard and do full-blown gradient shading and have 100 colors in my PNG. I'd prefer to use however many colors are necessary to create a good-looking pokemon-ish sprite. Although I haven't been counting colors on anyone else's sprites -- from what I've seen, it looks like everyone is sticking to a reasonably small color palette.
I'd like some input on the possible color palette I will use for my sprite. Since I am working on the back sprite, I'll use it for illustration purposes. Here is my current backsprite, with three different color palettes. 18 colors, 16 colors, and 15 colors.
18 colors ->
16 colors ->
15 colors ->
The eighteen color version looks best artistically, and utilizes all the colors I think are "necessary" to render the sprite in the way I consider "properly". Take note that I am intentionally half-toning on the purple joints and armbands. I could easily add another half-shade of purple and have a more gradual color transition. BUT, half-toning (aka dithering) is commonly used in pokemon sprites (particularly backsprites). So I think the dithering makes the sprite look more "pokemon-ish", even though artistically, I could make it smoother with the simple addition of another color. I'm sticking with the dithering.
In the 18-color version, I am using a few half-shades to smooth some color transitions, particularly in the hands. I've spent a lot of time on the hands of my sprites, and I've used several colors in the hands to express all the subtle nuances of the hand posing and design. This was very intentional on my part.
In the 16 color version, I removed some half-shades in the head, which doesn't affect the overall aesthetic of the sprite very much at all. The hands are still "fully shaded".
In the 15-color version, I removed one of the half-shades in the hands. This creates a more distinct color transition to the shaded areas of the hands.
So, here's the dilemma -- Which color palette is best? The bigger palette looks artistically smoother, but some may think it is "too smooth". The smaller palettes have more abrupt color transitions, but people may think they look "more pokemon-ish" and therefore preferable.
Since my entire sprite project has been a personal exercise in listening to feedback from others, I figured I'd solicit some comments on this as well. If this stuff is too detailed for you to notice any real difference, that's fine too.
