That's absolutely true. In some cartoon renderings I don't see that being used, though. Just dropping the L* slider value to get a shadow tone will only work in some cases. You guys mention how important coloured illumination (or coloured ambient light) is. After analysing some more toon media and those previous images…
It doesn't matter much whether it's realistic or stylized, shadows are always more saturated than most people think they are. What gives them colour is the reflected light from the sky or the object that is casting the shadows, often a mix of both. That is why shadows are often a bluish hue if the sky is clear and blue and…
I am 90% sure that some of those earlier examples just use HSL sliders instead of HSB. Also, check pixel art dedicated websites, they have some basic examples of stylised ramp building. In particular, a common advice is to hue-shift towards blue because typical stylised colors are made with the assumption that shadows are…
Hey Muzz, thank you so much. The braincells started working. Getting the terminology right seems to help with this. The "problem" that looks like the desaturation of shadows is described in that same quote from David's website. There's a TL,DR at the end of this post. There are two measurements of the "purity" of colour…
