creating graphic img for website

i needs some help creating a graphic image for a website - currently there are three images being used as button and i need a 4th one - i would like to change the colors for the 4th button. i will attach the existing three buttons and a mockup of the 4th button i'd like to have created. ## Deliverables i have attached the existing three graphic images being used for buttons and a mock up of the new button colors and text - please ignore the black outline - i want the new button to look like the other buttons except for the colors and the text. i may need to modify the color combination of the new button.
