This is a fairly easy thing to do. you will see numbers with the symbol # before them. That is your color code.
All you want to do is change the numbers to the color code of your choice.

In the following link you are brought to an unlimitless amount of colors. From there just copy and paste the code where you want it to go.

Be sure to leave the # before the number, or else you will not see the changes.

That should be that. If further help is needed or you run into a problem please let us know here. :)
