OKLCH to HEX: #E0FFFF

Result

Values are shown at full precision, so converting back gives exactly #e0ffff. 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. input

   oklch(0.97786 0.03203 196.640)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.03069
   b = C·sin H = -0.00917

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.963718
   m′ = L − 0.1056·a − 0.0639·b = 0.981685
   s′ = L − 0.0895·a − 1.2915·b = 0.992452

4. 4. cube

   l = 0.963718³ = 0.895054
   m = 0.981685³ = 0.946056
   s = 0.992452³ = 0.977526

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.745404
   G = −1.2684·l + 2.6098·m − 0.3413·s = 1.000007
   B = −0.0042·l − 0.7034·m + 1.7076·s = 1.000008

6. 6. linear → sRGB, × 255

   R = 0.87843 × 255 = 224.00 → 224
   G = 1.00000 × 255 = 255.00 → 255
   B = 1.00000 × 255 = 255.00 → 255

7. 7. RGB → HEX
