Color inaccuracy in 3D photos

[bdeck17]

Does anyone know how to get colors to render more accurately when rendering the 3D photos? I know lighting has a bit to do with it, but colors definitely do not render anywhere close to their true color codes.

Prefer textures to colors or put darker colors.

Exterior colors may be different in the morning or the evening when sun color is yellowish. Inside, choose pure white color sources if you don't want the hue to change under lights.
