Mit's Sprites and Such

[Previous]

EDIT: I've been looking at your 8-bit kirby sheet and have concluded it is not 8-bit
Though following NES rules its colour depth is far beyond that of 8-bit.
8-bit colour is
R3 G3 B2
Red and Green channel can have the following values (0-255 format) 0, 36, 73, 109, 146, 182, 219, 255
And blue channel can have the following values (0-255 format) 0, 85, 170, 255
its a common mistake and though I do enjoy the style, the limitations may increase your contrast which is a bit lacking in that particular sheet.

Sorry to drop in and derail further but I just have to state that you are just as wrong! :>
For one, if people talk about "8-bit" sprites, they usually don't talk about colour depth, but 8-bit gaming system limitations - usually NES. Of course, it's a wrong and misleading term and should be avoided, people should refer to the actual console instead (different 8-bit consoles have different limitations, too).
Then, your definition of 8-bit colour is too specialised. You have given the RGB332 example - however RGB233 and RGB323 are 8-bit colours, too. Even ARGB1223 etc. can be considered 8-bit colours - or ARGB2222. If we branch out into the field of 8-bit colour graphics (instead of colour depth), you can have indexed colour images with a palette of 256 colours, too, where the palette can have a larger colour depth (RGB888, for example, 24bpp True Colour) and each pixel uses eight bits to specify which palette colour it uses.
As in, what you did was interpret "8-bit" as "8-bit colour depth", whereas it could have been read as "8-bit colour graphic" or "a sprite as it could have been on an 8-bit console".
However, to sum it up, the point is that 8-bit is a vague, easily misinterpretable term that should be avoided. If you want to make a sprite "that could have been used on the NES", specify that instead of saying "8-bit" and you're way better off.


PS (concerning the post below):
I'm sorry but guess what, most 8-bit gaming consoles used predefined palettes so the colour depth doesn't depend on any such parameters :-)
Then there are systems using YPbBr so the 8-bit RGB colour depth rules do not apply in their way.
