Geometric wall decor

Quick decor project.  I bought these frames from goodwill and realized they were super hard to take apart to put a new pic inside.  So, instead I just masking taped off the blue frame part and decided to paint right on the glass in front of the other photo, I mean why not?  I just wanted something quick, so I painted a multicolored background and then taped off triangles & painted them black.  The colors go perfectly in my house, but you could use any colors/patterns you want!

Need:
-paint
-masking tape
-old frames pics
