I'm in the process of switching my theme to Graphene, but I have a question that I cannot seem to find a clear solution for. I believe to do what I want I need to add some custom CSS and possibly add icons/sprites or something similar, but here's the question.
Currently, the basic install of Graphene has the calendar icon or sprite as being grey. I would like to change that to a colour, to be precise, twelve different ones, one for each month of the year.
Can anyone please give me a clear method of doing this? Please keep in mind that I am very much a beginner at using CSS and very clear instructions would be appreciated. Thank you!
