9 brand violets, from the darkest to the lightest — and the numbers that actually tell them apart.
Darkest to lightest, left to right. Every band links to that brand's page — the full list, with numbers, is below.
Lightness
The set runs from Visa at L 30% to Twitch at L 59% — a spread of 29 points. Everything else here sits between those two.
Saturation
Twitch is the most saturated at C 0.255; Milka is the quietest at C 0.107 — 2.4× less colour at the same hue angle.
Same lightness, different intensity
Viber and Milka are equally light (L 59% and L 57%), but the first is far more saturated (C 0.210 against 0.107). Side by side that reads as "louder", not as "lighter".
Closest pair
FedEx #4D148C and Cadbury #4B0983 are 0.021 apart in OKLab — close enough that most people would not name them as two different colours without seeing them together.
Hue spread
All of these are violet by hue angle (268°–312° in OKLCH), but not by the same amount: Visa is at H 272° and Roku at H 307° — the low end sits next to blue, the high end leans into magenta.
How to read the numbers. OKLCH describes a colour the way the eye sees it: L is lightness (0% black, 100% white), C is chroma — how much colour is left when you take the grey out — and H is the hue angle on the colour wheel. Two colours with the same L look equally strong on a page even when their HEX values look nothing alike.
