Shader complexity on Mac

For testing the shader complexity I do not have a chromatic response. It only displays me black and blue but I do not have a reference to the green or red… I use an iMac (Nvidea GeForce GTX 780M 4096 MB) and I’m developing a game for kids for Mobile both iOS and Android. How can I fix this? It also happens to me on a MacBookPro.
