Make sure the effect of any local light sources remain in tact in terms of colour as in the example shown to the left.

When working with reflective surfaces, make sure that any colour adjustments made don't remove the colour of reflections or change them too much. Distinguishable reflections such as trees or props need to keep their original colour as in the example on the left.

The product being colour corrected may reflect colours from the other areas in the room (this is particularly visible when working with light or neutral colours).

Try to preserve some of the bounced colour effect visible in the original render where possible to maintain realism.

Although the original rendered image is a good guide to where bounce effect will occur, the effect is sometimes a little strong and needs to be reduced so that it isn't distracting, use your judgement on this.

We aim to match the mid tone of any product to within 5 percent of the supplied reference.

As well as matching the mid tones remember to check the saturation of highlights and shadows to ensure that they are realistic and in line with the reference, the original render is also a good indicator of how a material will behave in highlights and shadows and a good second reference.

Make sure that any colour adjustments are consistent across the suite of images being colour corrected. Toggling through colour corrected images in a set can help in spotting inconsistencies.
