7 derived colours are outside sRGB
Rotating hue at this chroma produces colours a normal screen cannot display, so they have been clipped to the nearest sRGB colour. The hex values shown are therefore not exactly what the maths asked for, and the harmony will look slightly less even than it should.
Fix: Lower the chroma of the input colour before deriving harmonies, or accept the clipped values as an approximation.
Note
CMYK here is a naive conversion
CMYK has no fixed meaning without an output profile — the same numbers print differently on different presses and papers. The value shown is the standard arithmetic conversion, not a colour-managed one.
Fix: For print work, convert in software with the press profile applied.
