There are a few things you can do to change the color of a logo in Photoshop. The first is to open the Colors palette and select a color. Then, use the eyedropper tool to select a color from the palette and set it as the logo’s primary color. You can also use the Hue/Saturation slider to adjust how bright or dark that color is. Finally, use the Mask tool to create a mask that covers all of the logo’s colors and then use the Clone Stamp tool to create copies of that mask and place them around your logo.
