Change the settings for the red, green and yellow materials to match the following. (Leave the diffuse colors alone) Adjust the Refl. glossiness to .85. The lower the value the more glossy the material.

Render the image. Results should be similar to the image on the left.

LOWER THE REFRACTION GLOSSINESS
The refraction glossies has been lowered to.95. I find this to be a little counter intuitive, but to increase glossieness you have to lower the spinner.

Note the increase in render time. For animations you might want to find another way to achieve this effect. Remember we are still using Basic render settings. Our custom Irradiance Map (IR Map) is setup for quick rendering. Higher quality IR maps will and higher output resolutions will significantly increase render times. That being said I have managed to render animations with moving objects using these "low" custom IR map settings without any noticable "flickering."
