How to consider phenotype in determining ideal colouring?

[hyperbeast]

Say I had A10 blue eyes and all the resources needed to change my colouring. I could achieve the 'ideal' colouring of black hair, light blue eyes and pale skin if I wanted to, but the question is if my pheno will make that colouring look uncanny and unharmonious.
do I just copy my phenos colouring from the images on humanphenotypes.net or is there a smarter way
