What you could try is shifting the colours or changing the colour balance.

After edge detection you:
1. Select Image > Adjust > Hue/Lightness/Saturation
2. In "Adjust Hue/Lightness/Saturation" dialog you set saturation to 40 (for example). Select a "Hue" of your desire. Use saturation and lightness till you've found the colour of your desire.
3. Confirm with "OK"

Alternatively you can:
1. Select Image > Adjust > Brightness/Contrast/Gamma/Balance
2. Use Red / Green / Blue sliders in "Colour Balance" panel to change the colour.

It might well be that contrast isn't strong enough. Use Image > Adjust > Brightness/Contrast/Gamma/Balance to increase contrast.
