Anyone know spectrophotometry?

[James3shin]

I know that the colors our eyes perceive are the wavelengths that are not* absorbed or impeded by the object. Well I've come across a question that states:

Explain why a solution that absorbs optimally at 410nm will appear yellow in color to the eye.

So Blue (UV) light is being absorbed, or White light - Blue = Yellow....is there a quantitative formula or trick?

edit: I forgot "Not"

Wouldn't you see yellow because it absorbs all colors of the visible light spectrum except for the yellow wavelength that enters your eye?

That's what I figured as well, but since the object is absorbing 410nm (UV), Red, Orange, Yellow, Green are still available for our eyes to process no?

Absorbs blue, leaves red and green, red and green combine to make yellow?
