A Few Things to Remember

Some people find it difficult to distinguish green color from red (red–green color blindness affects up to 8% of males and 0.5% of females). There are also forms of blue-yellow and gray (either color cannot be distinguished from gray) colorblindness. If you use these colors in a combination never employ color as the only way of differentiating UI elements – play with geo forms of the buttons, different fonts or layouts.

Keep in mind that in different countries there are cultural differences in how color is perceived. While in Europe or USA red color usually communicates danger (road signs, stop light etc.) in China red symbolizes good fortune and joy.
