Google Adsense allows you to choose the color styles of your ads. The text ads usually have an arrow besides them. The color of this arrow is usually defined by the color you set as the link color. However, Google changes the color slightly.
For example when I set the link color to #d83f3f the resulting ad will display the arrow as #e16f6f.
I want you to create a page where I can specify what color the arrow should be and it will generate a hex code to put into adsense that will generate that exact color.
I cannot give you access to my adsense account, so please old bid on the project if you have your own adsense account to do testing.
