Press Ctrl/Cmd+Shift+U to desaturate the colors.
Removing the color, allows you to see the tones clearly. They are muddy.
Press Ctrl/Cmd+L for levels (Don’t use an adjustment layer – you won’t hear me say that often).
Move the white slider (triangle) to the left to clean the highlights, it should be where the pixels start on the histogram as pictured.
Nudge the gray mid-tone slider a little to get the contrast you desire.
Choose Filter>Neural Filter>Colorize
This time we get a more pleasing and controlled result.
