Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. input
```
oklch(0.77088 0.21557 132.451)
```

2. OKLCH → Oklab

a = C·cos H = -0.14550
b = C·sin H = 0.15906

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.747538
m′ = L − 0.1056·a − 0.0639·b = 0.776083
s′ = L − 0.0895·a − 1.2915·b = 0.578477

4. cube

l = 0.747538³ = 0.417734
m = 0.776083³ = 0.467438
s = 0.578477³ = 0.193579

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.201555
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.623957
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.000001

6. linear → sRGB, × 255

R = 0.48627 × 255 = 124.00 → 124
G = 0.81176 × 255 = 207.00 → 207
B = 0.00002 × 255 = 0.00 → 0

7. RGB → HEX
```
#7CCF00
```
