Also known as: Tailwind olive-800

oklch(0.28601 0.01583 107.360) → #2B2B22

Values are shown at full precision, so converting back gives exactly #2b2b22. 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(0.28601 0.01583 107.360)
```

2. OKLCH → Oklab

a = C·cos H = -0.00472
b = C·sin H = 0.01511

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.287399
m′ = L − 0.1056·a − 0.0639·b = 0.285544
s′ = L − 0.0895·a − 1.2915·b = 0.266920

4. cube

l = 0.287399³ = 0.023739
m = 0.285544³ = 0.023282
s = 0.266920³ = 0.019017

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.024158
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.024158
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.015997

6. linear → sRGB, × 255

R = 0.16863 × 255 = 43.00 → 43
G = 0.16863 × 255 = 43.00 → 43
B = 0.13334 × 255 = 34.00 → 34

7. RGB → HEX
```
#2B2B22
```
