| | Basically, these are simplified stories we tell – and not just to children – when we want to begin to explain something, but feel that our audience doesn’t have the background information necessary to understand the “full” story. These can be anything from “the stork brought you” to “Columbus wanted to prove that the Earth was round” to “atoms look like little solar systems” to “evolution is the survival of the fittest.” | | Basically, these are simplified stories we tell – and not just to children – when we want to begin to explain something, but feel that our audience doesn’t have the background information necessary to understand the “full” story.

| − | The fundamental issue that this comic vaguely touches on, but doesn't really address, is that any given object actually has three different colours and people often overlook this.
| |
| − |
| |
| − | *Emission colour - This is the colour that the object appears without external illumination.
| |
| − | *Transmission colour - This is the colour that the object imparts to a (white) light source when illuminated from behind.
| |
| − | *Reflection colour - This is the colour that the object imparts to a (white) light source when illuminated from in front.

| − | Obviously, an object that doesn't emit light has an emission colour of "black". An object that is opaque has a transmission colour of "black". Because many objects have these properties, and most of the non-opaque objects have similar transmission and reflection colours, it's easy for people to overlook the three different colours of objects and say for instance "plants are green" when technically they mean "plants are black/green/green" or "the sun is white" when technically they mean "the sun is white/black/black".

| − | The thing that makes air stick out is that it has a reflection colour of pale blue, but a transmission colour of orange/red. The reason ''why'' is that its colour derives from Rayleigh scattering rather than absorption. (Air's emission colour is black, unless strongly heated.)
