OKLCH to HEX: #B0E0E6

Also known as: CSS powderblue

oklch(0.87508 0.05020 205.731) → #B0E0E6

Values are shown at full precision, so converting back gives exactly #b0e0e6. 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. input
```
oklch(0.87508 0.05020 205.731)
```

2. OKLCH → Oklab

a = C·cos H = -0.04522
b = C·sin H = -0.02179

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.852453
m′ = L − 0.1056·a − 0.0639·b = 0.881245
s′ = L − 0.0895·a − 1.2915·b = 0.907274

4. cube

l = 0.852453³ = 0.619458
m = 0.881245³ = 0.684369
s = 0.907274³ = 0.746818

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.434167
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.745390
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.791280

6. linear → sRGB, × 255

R = 0.69021 × 255 = 176.00 → 176
G = 0.87842 × 255 = 224.00 → 224
B = 0.90195 × 255 = 230.00 → 230

7. RGB → HEX
```
#B0E0E6
```
