Remove a navy background
Free, no signup, and your image never leaves your device.
Pick the navy with the eyedropper and it is keyed out everywhere it appears. The numbers below are the ones this tool actually uses, so you can set it up in one go.
#001f54 · rgb(0, 31, 84)
| Hex | #001f54 |
|---|---|
| RGB | 0, 31, 84 |
| CIE L*a*b* | L* 13.4 a* 13.6 b* -35.2 |
| Relative luminance | 2% |
| Match radius at the suggested tolerance | ΔE 6.9 |
Why this tolerance
Dark colours compress poorly and carry most of an image's noise, so the tolerance has to cover a wider spread than the flat appearance suggests — while still staying clear of dark parts of the subject.

When this works well
A flat or near-flat navy area that is clearly different from your subject. Compression noise and lighting variation are expected — that is what the tolerance absorbs. Where it struggles is a subject containing the same navy, and there the brush is faster than any amount of slider tuning.
Common questions
What tolerance should I use for a navy background?
Start at 34 and adjust from there. Raise it if flecks of navy survive; lower it if the subject starts disappearing.
It removed part of my subject as well. What now?
The subject contains something close to that navy. Lower the tolerance until the subject is safe, accept the leftover specks, and remove those with the brush — that is reliably faster than finding a tolerance that does both.
Does it remove navy inside the subject too?
Only if you want it to. Leave connectivity on and only the area joined to the edges goes; turn it off and every matching pixel goes, including enclosed gaps.
