use pattern psd tutorial1. Open the pattern psd. Open your color scheme.
This is mine, which you can find on this website.
2. Change the fill layer colors to match your own color scheme colors
(>> click here << if you don't know how to change a fill layers colors).
This is before I changed the colors
This is after I changed them
and this is what my pattern looks like now
3. IF you need to define this pattern on Photshop:
Click on any layer except one of the color fill layers. (could also merge all of the layers together OR create a new layer. It just can't be a fill layer) and then define the pattern
