Why the wheel you learned at school disagrees with the one in your design software, and which to use when.

The 60-30-10 rule
A proportion borrowed from interior design that solves most "my palette looks messy" problems in one step.
Color psychology, carefully
What colours reliably do, what depends on culture, and how to use the difference without overclaiming.
Color that everyone can read
Contrast ratios, colour blindness and the two habits that fix most accessibility problems.
Seasonal color analysis, explained
Where the twelve-season system comes from, what the four dimensions actually measure, and how to use it beyond clothes.
