This video tutorial will show you how to change the colour tints of your png overlays in photoshop.
❤️ P.S! A little tip that I didn't include in the video is using your BLENDING MODES with the colour layer.
❤️ Sometimes it will not blend so well. By changing the blending mode of the colour tint to the blending mode COLOUR, it will blend the colour much better. Play around with that, because this will help when the colour is too solid.
