HEX to OKLCH: #14532D

Result

Values are shown at full precision, so converting back gives exactly #14532d. 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: 20/255 = 0.07843 → 0.006995  (((x + 0.055) / 1.055)^2.4)
   G: 83/255 = 0.32549 → 0.086500  (((x + 0.055) / 1.055)^2.4)
   B: 45/255 = 0.17647 → 0.026241  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.050627
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.063181
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.041518

3. 3. cube root

   l′ = ∛0.050627 = 0.369936
   m′ = ∛0.063181 = 0.398287
   s′ = ∛0.041518 = 0.346268

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.39253
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.07952
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.04133

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.08962
   H = atan2(b, a) = 152.535°
   L = 0.39253

6. 6. OKLCH

   oklch(0.39253 0.08962 152.535)
   rounded: oklch(0.393 0.090 152.5)
