HEX to OKLCH: #EAB308

Result

Values are shown at full precision, so converting back gives exactly #eab308. 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: 234/255 = 0.91765 → 0.822786  (((x + 0.055) / 1.055)^2.4)
   G: 179/255 = 0.70196 → 0.450786  (((x + 0.055) / 1.055)^2.4)
   B: 8/255 = 0.03137 → 0.002428  (÷ 12.92)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.581066
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.481462
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.201179

3. 3. cube root

   l′ = ∛0.581066 = 0.834466
   m′ = ∛0.481462 = 0.783767
   s′ = ∛0.201179 = 0.585950

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.79524
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.01115
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.16128

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.16167
   H = atan2(b, a) = 86.047°
   L = 0.79524

6. 6. OKLCH

   oklch(0.79524 0.16167 86.047)
   rounded: oklch(0.795 0.162 86.0)
