Many thanks to Jmorphman for making this sheet.
This post will cover colour separation and my reasoning behind doing so. Yes I always separate for good reason. The project I've been working on since....can't remember should be revealed soon. Anyway.Let's take a newer(ish) sprite which has a few limitations:Now lets look at the palettes that the character has in game so we can make note of the limitationsBecause of the use of the darkest colour (0,0,0) on several parts of the sprite, creating a palette with a light coloured top is inadvisable. Why?That's why.So this is where separation is helpful. As I'm sure you know, you can separate colours which will allow you to make palettes that were not possible before.Simply by separating the hair (and for good measure, the frames of the shades) you can create a nice looking palette. When you've got a template like this, you can start to ask, "what is worth separating?" In this situation, I would go on to separate her eyes (both the pupils and giving colour to her irises) the eyes on the frog on her shirt, her gloves, the frames of her shades, the belt (or at least the Taegeuk) and her shoes.If you really wanted to go extra, you could separate the stripes on her pants the trims on her gloves and shirt. Why am I rambling? Because I wanted to know what you think of colour separation in sprites. For the most part, I think that it's only worth it if the palettes that are made are good. Lets face it, when everything is separated, people will try to go too far with their palette making and end up making something familiar to the bad example I showed (ie, taking away the "look" of the sprite). I'm quite interested to hear what others think. If there are enough responses, I can explain in detail how I do colour separation.
