Actually pretty much the very opposite happens.
The standard include files (including `colors.inc`) have the following
#declare Foo_Inc_Temp = version;
#version 3.5; // typical; value may differ
This structure is designed to reset the effective language version back
to whatever it was before the include file.
There is a problem with this construct however: In v3.7.0, the effective
language version defaults to v3.6.2 for backwards compatibility, but the
`version` keyword, when used as an expression, defaults to the actual
software version, i.e. 3.7.
Thus, when a scene has no `#version` statement of its own and includes
one of the standard include files, the last `#version` statement in that
file does not reset the effective language version back to the default
of v3.6.2, but rather sets it to the actual software version, which is
v3.7.0 in that case.
This behaviour has been changed in later versions.
