CMYK here is the plain formula with no colour profile, so treat it as a starting point; a printer's profile gives the real ink values. CIELAB uses a D50 white point, as CSS lab() does. HSV is not a CSS function, so it is shown for design apps only.

How it looks with colour blindness

Normal vision#cbfcff Protanopia#f5f7ff Deuteranopia#ebf0ff Tritanopia#bbfffd Achromatopsia#f3f3f3

Simulated with the Machado, Oliveira and Fernandes (2009) matrices at full severity, applied in linear RGB; achromatopsia shows the colour's luminance as grey. Milder forms (protanomaly, deuteranomaly) are far more common and shift colours less. Never use colour as the only way to carry meaning.
