Select colour and bump output and set blending mode to Linear Interpol 2

To add colour to our texture we will add colour to component 1. Buttons C (colour) and B (bump) should be lit and button A (alpha) should be off. If they're not, click them to set them correctly.

Click on the small triangle in the bottomleft corner of component 1 : this will open a selection of colour blending modes. 
Choose Linear Interpol 2, which interpolates the colour from the top two colour circles. 
Select colour setting with Alt-Leftclick and set colours
Now open the colour Dialog for colour circle 1 (the topmost circle) by Alt(Opt)-clicking that circle.
 (Just clicking on the circle gives you a colour sampler which gives you a much cruder control unless of course you want to quickly pick up a colour from somewhere else on the screen.)
Select HLS and slide the Hue , Light and Saturation settings till you get the colour you like : you can watch it in the topright corner. The one on the left is what it looked like before you started changing the settings. 
The use of HLS is just a matter of personal preference : it's the one I'm used to. 

Repeat this for the second colour circle. Try to get colours that don't differ too much : it'll look more natural. 


Opening the Noise editor Now we've gotten this far , we'll save our texture in the Texture Library.

To open the texture Library , cllick the UPPER button on the right of the combination window. 
The bottom one would randomize our texture, ruining all our efforts. 
Ctrl (Command)-Z would save us unless we accidentally clicked the randomize button twice.

(Make a habit of saving your textures regularly while working on them. You can always delete the unwanted ones from the Texture library later, but it bites to lose hours of work because you click the wrong button or your PC crashes.)


 
Opening the Texture Library and adding the texture in Rocks Naming our new texture
 
The Texture library opens and our texture appears in the preview window and guess what : it looks really AWFUL !
Don't worry : click the arrow at the righthand bottom of the preview and select Show bump. Now, that's more like it. 
Now click Rocks and click Add. You can save this texture under another category, but Rocks seemed like the obvious choice. 
Give it a name you like and add a little description if you want and enter it with the check mark: it will now show up in a little square of its own behind all the other textures. 
Close the texture library with the check mark and close the DTE with the check mark so we're back in the Materials lab. 

 
Set Ambient and Bump Select Ambient and Bump  ( Diffuse was already selected ), so the texture gives our material Diffuse and Ambient colour and Bump. 

Slide the Bump Height setting to about 24-25 so it won't look flat.
