The visible, colored part of the eye that controls pupil dilation is the iris.
colored light spectrum
visible light waves
The nuclear membrane and the nucleolus.
I would imagine because the wavelength of electrons is not in the visible region
This is called the (visible) spectrum; and may also be referred to as a rainbow.
colored light spectrum
The electronic structure of the iron ions that are contained in it. Iron is a transition metal, and transition metal compounds tend to be highly colored because they have absorption bands in the visible spectrum.

Opacity slider controls how much is visible of layer content. 100% is everything visible, 0% nothing visible, 50% you can see through.
Yes, it is.
visible light waves
[The colored part of the eye: brown, green, blue, etc. ... is called the macula,]The macula is a small spot in the back of the eye, and not visible from the outside without instruments. The visible part around the pupil is the iris.
the nucleolus
china wall
The Great Wall of China
The nuclear membrane and the nucleolus.
The fact the solution is colored means that it absorbs (or interacts at least) with visible (since you can see it!). Generally such compounds are characterized using visible light, but also ultraviolet (UV) and infrared (IR) which are the two regions of the electromagnetic spectrum adjacent to visible light. This type of analysis is generally called UV/visible spectroscopy (although it frequently also extends into the near IR region).
