    Perhaps you could try Burn tool with Range: Highlights – Joonas Dec 16 '15 at 19:33

    You can also select by color, sharpen the selection (Select -> Sharpen), fill the whole area. – Paolo Gibellini Dec 16 '15 at 23:10

If this is not solved yet, use the Threshold tool in Colors tab. Adjust slider to achieve desired result.
