Changing colour of a diagram

Hello, I've been searching for hours trying to figure this out. So I'd be grateful for any help.

I have a psd image that I opened in gimp - it is a b/w pic of a character (line drawing) and some words. I want to change the colour of the character and words.

Sounds simple - but I can only see how to "fill" not change the actual lines that have been drawn

Is this possible - can someone point me to the right tutorial please/or provide instructions.

Many thanks, JP

There are different ways to get a result depending on the original .psd image.

Since you say it is black and white, When you open in Gimp ***check that the color mode is RGB*** and change if necessary.

Image menu -> Mode -> RGB You might have something like this: http://imgur.com/MPwO1ie

If it is black on white, then add a layer on top and fill it with the new colour. Now set the Layer Mode to Screen. looks like this: http://imgur.com/rCnSJ3D

If the diagram is black on transparent then enable the ***alpha lock*** for that layer and fill the layer with the new colour. looks like this: http://imgur.com/VrbA8NR

PS text layers imported into Gimp are 'rasterized' (no longer editable text) treat these the same as previous, set the alpha lock, bucket fill. example: http://imgur.com/jH797l5

Many thanks for your help and including pictures. I can't get the layer menu up to choose screen, but I am new here and will search through the help. The rest makes sense so far. Thanks again.

Many thanks for your help and including pictures. I can't get the layer menu up to choose screen,

Use the Gimp menu Windows -> Dockable Dialogs -> Layers or the shortcut ctrl-L (for OSX ctrl might be command)

Then choosing the layer mode is via the drop down menu top of the dialog, for a description, see about half way down this page

Sounds like you have a less-than-standard Gimp setup but that is another issue.
