Also known as: Tailwind emerald-950

oklch(0.26133 0.05013 173.096) → #002C22

Values are shown at full precision, so converting back gives exactly #002c22. 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(0.26133 0.05013 173.096)
```

2. OKLCH → Oklab

a = C·cos H = -0.04977
b = C·sin H = 0.00603

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.242906
m′ = L − 0.1056·a − 0.0639·b = 0.266199
s′ = L − 0.0895·a − 1.2915·b = 0.258001

4. cube

l = 0.242906³ = 0.014332
m = 0.266199³ = 0.018863
s = 0.258001³ = 0.017174

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.000001
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.025187
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.015997

6. linear → sRGB, × 255

R = 0.00002 × 255 = 0.00 → 0
G = 0.17255 × 255 = 44.00 → 44
B = 0.13334 × 255 = 34.00 → 34

7. RGB → HEX
```
#002C22
```
