Need to replace color with a nearby color

[defaultrl4ryxnhxbps]

I have attached a sample image. I need to replace the black with a nearby color so that there is no black separating the colors. The image has multiple areas like this. Any tips on how to get this done as painless as possible? Doesn't have to be too clean.

I got some decent results doing this:

1. Select > Color Range to select the black areas (use a relatively high Fuzziness setting to get all the black)
2. Expand the selection by 2 pixels, to get the border regions
3. Feather the selection by 2 pixels to smooth things out
4. Edit > Fill and use Content-Aware Fill for the Contents.

You may have to fiddle with the settings (Fuzziness, Expand, and Feather) to get the look you are going for
