Convert color of graphic

Hi all, I think this is a simple project for any experienced graphic designer. Take the two attached graphic (attached in .ZIP file below) and convert them into grey or black shades (whichever looks better) instead of their existing colors, while still keeping the "fading" effects on the graphics themselves. Plus maybe add in a little touch of light orange somewhere on the graphic where its artistic looking. They will be used in a logo design later. Should be delivered in high-quality JPG or .GIF formats (your choice). Thanks and SAMPLES if possible so I can see that you can do the job. ## Deliverables Altered 2 graphic files. ## Platform Windows, GIF or JPG
