Thinking about painting inside of my box white.

Got this idea that different shades of white paint reflect light differently but the question is:

is there BIG difference of reflective properties between shades of white color to be of a significant value?

If one shade of white reflect like 30% more maybe its worth it but could it be that much?
maybe its in ten percent range?

is it possible to measure this with some light meter?
.......

Behr White Paint

Behr White Paint

From my research Behr's 4850 Ultra White paint is the most economical 85% reflective paint. It is sold at Home Depot. Good stuff.

Added data point, “titanium white”

What you need is a REAL white, not an off-white or an eggshell, and you need enough for three coats. Density/saturation improves with successive coats. Let each coat dry thoroughly.

Flat white is better than any level of shine IMO.
