Photoshop
In most
Photoshop programs, their is a tool bar with all of your tools on either the far right or far left of your screen. On that tool bar, their should be a small 'T' as one of the options, typically on the right side (if the tool bar is in two rows). Click on that, and either a text box will appear, automatically creating a new layer specifically for text, or you will have to draw a box. Both options will create a new layer. Then, when you're done having your box created, just type, and the letters will be on the new layer. Once finished, you can rasterize the layer (by right-clicking on it) to turn it into a regular layer, and you can then colour the text any way you like, even using gradients. But make sure you lock the layer, first!
