This question already has an answer here:

Exactly as title says. I do not know why I am having so much trouble with this. I have googled many solutions and I cannot find a straightforward answer.

Also, the only method I know is "Gridlines" and there is no option to change colour

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

PlotStyle? Do not g**gle, press F1. And about GridLines, well, there is an option GridLinesStyle too. – Kuba Sep 20 '13 at 2:21
Perfect, thank you! – Hawk Sep 20 '13 at 2:26

Here's an example that uses GridLines that are specific colors at specific positions:

Plot[Sin[x], {x, 0, 10}, PlotStyle -> Directive[Red, Thick], 
 GridLines -> {{{Pi, Blue}, {3 Pi, Orange}}, None}]
