Are the full charsets your final (or at least most recent) decision on the most appropriate palette? Compared to the large selection of front views, your top two charsets here use less saturated midtones, yellower highlights and bluer shadows, all with a brighter value in general, and I'm wondering what decided that as the best choice.
I've started studying your palette choice here and noticed a few things, as per your post in the HKCP topic. Maybe you can enlighten me on their relevance - perhaps it's all just personal preference, perhaps you've practiced about to find some things work better.
Clothing shifts strongly to violet/purple shadows and yellow highlights. Pieces usually done in six shades, except for where there are areas of excessive shadow (typically where full body sets share the same colour).
Hair hue-shifts only to a very, very small degree towards yellow/purple (and indeed in some cases goes the other way for 'unusual' hair, such as with glasses-ragged-cape man). Done in six shades as well, sometimes five.
So you usually create your colour swatches as six pieces?
When it comes to tilesets, do you create your palette/swatches in sets of six as well, or eight so you can have an extra bit of shadow for the tileset being darker/less saturated than characters?
Did you attempt to decide most of your clothing color choices in advance? I'm still attempting to understand how people decide that colours share the same contrast - as far as I can tell a set of colours sharing similar contrast seems to be contrast between the same shades of the colour, rather than sharing shades of contrast between different colours (being that purple looks darker than yellow, when you look at a palette it typically looks like a wave of darkness moves in towards purple/blue and out towards yellow/green/red).
I've read everything I could find on palette here and I'm studying as much as I can find online (WetCanvas - Color Theory & Mixing: 16 Lessons in Color Theory) but there sure is a lot to go through, so any tips that people who've already done the hard grind can share with us are vastly, vastly helpful.
