Also known as: Tailwind green-900

oklch(0.39347 0.09570 152.275) → #0D542B

Values are shown at full precision, so converting back gives exactly #0d542b. 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(0.39347 0.09570 152.275)
```

2. OKLCH → Oklab

a = C·cos H = -0.08471
b = C·sin H = 0.04452

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.369503
m′ = L − 0.1056·a − 0.0639·b = 0.399569
s′ = L − 0.0895·a − 1.2915·b = 0.343550

4. cube

l = 0.369503³ = 0.050449
m = 0.399569³ = 0.063794
s = 0.343550³ = 0.040548

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.004023
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.088654
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.024155

6. linear → sRGB, × 255

R = 0.05096 × 255 = 13.00 → 13
G = 0.32941 × 255 = 84.00 → 84
B = 0.16862 × 255 = 43.00 → 43

7. RGB → HEX
```
#0D542B
```
