While designing a web site layout in Photoshop, on a 960 grid, sometimes we want to put some extra guides to use along with our main guides.
Is there a way to give a separate color to some individual Guides?
All guides in Photoshop are controlled by the single color set in the Preferences. There is no way to have guides of varying color. And, in fact, this is true of all Adobe software.
That being posted, there's nothing stopping you from creating a layer with vector paths drawn on it to use as guides.
