I [came across this](https://github.com/chromium/chromium/commit/5deed17c9f1446cf0a061d7566e552e8e9bddfaf#diff-1bb6772ac74c6531ba9dd6432fcf301a1d29df66c36bc606e4ab924943ade602R1016) in Chrome:
```
// Legacy color channels get serialized with integers in the range [0,255].
// Channels that have a value of exactly 0.5 can get incorrectly rounded
// down to 127 when being converted to an integer. Add a small epsilon to
// avoid this. See crbug.com/1425856.
std::tie(r, g, b) =
gfx::SRGBToSRGBLegacy(r + kEpsilon, g + kEpsilon, b + kEpsilon);
```
