HEX to OKLCH: #C2410C

Result

Values are shown at full precision, so converting back gives exactly #c2410c. 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: 194/255 = 0.76078 → 0.539479  (((x + 0.055) / 1.055)^2.4)
   G: 65/255 = 0.25490 → 0.052861  (((x + 0.055) / 1.055)^2.4)
   B: 12/255 = 0.04706 → 0.003677  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.250925
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.150695
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.064845

3. 3. cube root

   l′ = ∛0.250925 = 0.630737
   m′ = ∛0.150695 = 0.532148
   s′ = ∛0.064845 = 0.401753

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.55343
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.13625
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.10800

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.17386
   H = atan2(b, a) = 38.402°
   L = 0.55343

6. 6. OKLCH

   oklch(0.55343 0.17386 38.402)
   rounded: oklch(0.553 0.174 38.4)
