change button image colors

I have two images I need modified with different colors. The modified images should be modified based on the following colors: #fec91b Yellow #680b7e Purple #07016f Blue The images should still have the slight gloss and gradient with the new colors... basically the exact same just different color. I have attached the images to be modified to this project post. any questions let me know... you can seen the current images on a test site here: [login to view URL] The green hover image and green hover left image are the two that need modified... (see attachement). I don't have the original PSD files. Finished project need to include original photoshop PSD files... and the 6 new images as PNGs
