Refractive index μ =( textreal depth/ textapparent depth) For red colour, refractive index is minimum, i.e., it will have maximum apparent depth and hence, appears least raised.

Refractive index
$μ = \frac{real depth}{apparent depth}$
For red colour, refractive index is minimum, i.e., it will have maximum apparent depth and hence, appears least raised.
