I want to change the color of a section of a document.
The command to do so is

colorred sectionIntroduction

(Merely doing sectioncolorIntroduction does not change the color of the section number).

So when I carry out the command above, it slightly adjusts the vertical space of all of the text in the entire document. This can be observed in the gif https://imgur.com/a/RLpPLU6

So, how do I carry out color changes without changing the vertical spacing, etc ?

Edit : A minimal code snippet and the effect of changing color can be seen here https://imgur.com/a/pI3NmuX (no other change except color)

sectionIntroduction

The promise of deep learning is to discover rich, hierarchical models that represent
probability distributions over the kinds of data encountered in artificial intelligence applications,
 such as natural images, audio waveforms containing speech, and symbols in natural language corpora.

This framework can yield specific training algorithms for many kinds of model and optimization
algorithm. In this article, we explore the special case when the generative model generates
samples by passing random noise through a multilayer perceptron, and the discriminative model
is also a multilayer perceptron. We refer to this special case as em adversarial nets.
In this case, we can train both models using only
the highly successful backpropagation and dropout algorithms
and sample from the generative
model using only forward propagation. No approximate inference or Markov chains are necessary.

I previously thought the culprit was the nips14submit_e (which can be found here (https://pastebin.com/aw96SzXB)), but it doesn't seem to be

I want to change the color of a section of a document ... one section at a time.

If you prefer using high-level commands and letting LaTeX perform most of the hard work for you "behind the scenes", while not having to be concerned with subtle positional shifts, I recommend loading the sectsty package and using its sectionfont command. As the following example shows, one can employ sectionfontcolor... multiple times.

As you can check with showoutput there are no spacing differences in the supplied example in the question with and without colorred so it isn't an example of this problem...

However the issue can occur (and is shown in the first posted gif with the centred abstract).

A real example is

If you uncomment the colour command you get additional space before the heading as the colour whatsit node prevents the section command "seeing" the vertical space already added by the endcenter and so it adds its full specified amount rather than merging the spaces specified by endcenter and section.

The trick is to do colour changes as far as possible in horizontal not vertical mode, so for example this works
