How would you simulate chromatic aberration like this? The angle of the ray depends on the frequency, so it seems like you would need to send different rays for each color.
@HelloWorld White light is made up of rays of different color, so I think this case would already be handled if you were dealing with colored light. You wouldn't be able to simulate something with both colored rays and then just a general "white light" since that would be redundant. This effect wouldn't show up if it was just one "color" of light.
