Change colour of eight icon images.

I have a set of icons attached (all transparent PNGs) that I need to have changed to several different colours.

Deliverables:
1. There is one green logo in the pack which should be converted to a simple "R" in white to match the other icons.
2. All icons in #D6B43C
3. All icons in #D7CA9B
4. Finally, all of the above must be high quality, non-pixelated, transparent PNGs.

Unfortunately I only have access to the icons attached.
