HEX to OKLCH: #BEF264

Result

Values are shown at full precision, so converting back gives exactly #bef264. The rounded form is what you normally paste into CSS.

Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. 1. sRGB → linear

   R: 190/255 = 0.74510 → 0.514918  (((x + 0.055) / 1.055)^2.4)
   G: 242/255 = 0.94902 → 0.887923  (((x + 0.055) / 1.055)^2.4)
   B: 100/255 = 0.39216 → 0.127438  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.695038
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.727208
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.375896

3. 3. cube root

   l′ = ∛0.695038 = 0.885801
   m′ = ∛0.727208 = 0.899262
   s′ = ∛0.375896 = 0.721699

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.89715
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.10663
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.14324

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.17858
   H = atan2(b, a) = 126.665°
   L = 0.89715

6. 6. OKLCH

   oklch(0.89715 0.17858 126.665)
   rounded: oklch(0.897 0.179 126.7)
