Data Validation based on formula

I have a variable saved as a value, it is an average.  lets call it MyAvg.

I would like to apply a data validation on a column (D) that uses MyAvg that:

If value is >15% of MyAvg = Red
If value is between >10 of MyAvg but <15% of MyAvg = Yellow
If value is between <10 of MyAvg and -10% of MyAvg = Green

How would I write a formula in the Data Validation, to use MyAvg?
Ideally, or another option I would like to explore this using some VBA code against a cell... but was going to try both ways.  

Please advise and thanks.
