HEX to OKLCH: #065F46

Result

Values are shown at full precision, so converting back gives exactly #065f46. 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: 6/255 = 0.02353 → 0.001821  (÷ 12.92)
   G: 95/255 = 0.37255 → 0.114435  (((x + 0.055) / 1.055)^2.4)
   B: 70/255 = 0.27451 → 0.061246  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.065277
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.084860
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.070983

3. 3. cube root

   l′ = ∛0.065277 = 0.402643
   m′ = ∛0.084860 = 0.439441
   s′ = ∛0.070983 = 0.414049

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.43180
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.08423
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.01958

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.08647
   H = atan2(b, a) = 166.913°
   L = 0.43180

6. 6. OKLCH

   oklch(0.43180 0.08647 166.913)
   rounded: oklch(0.432 0.086 166.9)
