The rainbow effect in a prism is explained by the phenomenon of dispersion of light into different colours, with each colour, or wavelength of light, bending at a different angle.

Newton's experiments with prisms led to the understanding that natural (white) light is composed of a range of differently coloured beams.

In a comment the OP mentions coloured glass as an example of what is meant by absorption. If we take for example green glass, this is frequently coloured using iron (II) salts. Light is absorbed and promotes electrons between the $\text{Fe}^{2+}$ $3d$ orbitals (the $3d$ orbitals are split into different energies by the environment). The excited electrons relax by transferring energy to the surrounding chemical bonds as vibrational excitations, which turns the absorbed light into heat.

For example, when you shine white light into a prism, you observe a band of colours on the other side. This process isn't magic, but rather a scientific phenomenon known as dispersion of light.

What is absorption of lightin physics

In the domain of optics, a light prism is a transparent optical element with flat, polished surfaces that refract, or bend, light. Its form is typically a polished glass triangle and the light waves passing through it are both slowed and bent.

Newton's experiments with prisms in the 17th century led to a deeper understanding of the nature of light, proving that natural (white) light is composed of a range of differently coloured beams. This was a significant leap in the scientific understanding of light.

I found this question on a hobby science forum (mainly about chemistry) and found embarrassingly that I couldn't answer the question. A few searches along the lines of 'photons absorption' here on Ph.SE yielded surprisingly little.

What is absorption of lightin chemistry

If you move to very high-energy photons which are absorbed in the nucleus, the rules get messier but the basics are the same: the particles in the nucleus have their own set of energy states (or energy of fission) which have to match the photon energy. That's very top level, of course.

In a dense medium like a liquid or solid the atoms/molecules interact mechanically with their neighbours i.e. vibrations of the atom/molecule can be transmitted to neighbouring atoms/molecules and vice versa. In these conditions it is very likely that the excited atom/molecule will transfer its extra energy into mechanical vibrations before it has a chance to re-emit the energy as light. The end result is that the light is turned into vibrational energy i.e. heat.

Different prism angles and materials lead to variation in how dispersed or close the bands of colours are. This means the refraction and hence the spectrum witnessed can vary based on the properties of the prism.

A light prism is a transparent optical element with flat, polished surfaces that refract, or bend, light. It's typically a polished glass triangle and the light waves passing through it are both slowed and bent.

Light slows down and refracts or changes direction when it enters the prism. When it exits, it speeds up and refracts away from the normal. Different colors of light refract differently because they have different refractive indices, causing white light to split into a spectrum of colors.

If you start with an isolated atom or molecule, the a photon of the right frequency can be absorbed by exciting the atom/molecule to a higher energy state. Why this happens is discussed in my answer to How do photons know they can or can't excite electrons in atoms?. The excited state will decay back to the ground state and re-emit a photon. So the light is not lost though it may be scattered into a different direction.

The real answer is " quantum magic." Otherwise, it's simply an observed effect that a photon will be absorbed when its energy matches the transition energy of an electron (said electron gaining potential energy).
