HEX to OKLCH: #E7E4E7

Result

Values are shown at full precision, so converting back gives exactly #e7e4e7. 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: 231/255 = 0.90588 → 0.799103  (((x + 0.055) / 1.055)^2.4)
   G: 228/255 = 0.89412 → 0.775822  (((x + 0.055) / 1.055)^2.4)
   B: 231/255 = 0.90588 → 0.799103  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.786617
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.783256
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.792544

3. 3. cube root

   l′ = ∛0.786617 = 0.923112
   m′ = ∛0.783256 = 0.921795
   s′ = ∛0.792544 = 0.925425

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.92206
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.00424
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00290

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.00514
   H = atan2(b, a) = 325.618°
   L = 0.92206

6. 6. OKLCH

   oklch(0.92206 0.00514 325.618)
   rounded: oklch(0.922 0.005 325.6)
