HEX to OKLCH: #92400E

Result

Values are shown at full precision, so converting back gives exactly #92400e. 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: 146/255 = 0.57255 → 0.287441  (((x + 0.055) / 1.055)^2.4)
   G: 64/255 = 0.25098 → 0.051269  (((x + 0.055) / 1.055)^2.4)
   B: 14/255 = 0.05490 → 0.004391  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.146213
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.096280
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.042592

3. 3. cube root

   l′ = ∛0.146213 = 0.526819
   m′ = ∛0.096280 = 0.458331
   s′ = ∛0.042592 = 0.349228

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.47319
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.08631
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.09000

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.12470
   H = atan2(b, a) = 46.201°
   L = 0.47319

6. 6. OKLCH

   oklch(0.47319 0.12470 46.201)
   rounded: oklch(0.473 0.125 46.2)
