Statistical Analysis Help for a Psychology Project

I have a set of data and am really confused about which statistical tests i should use. Please Help!

So...

all participants take a test with 8 questions where they are awarded a mark for each correct answer. They then receive a final score out of 8. the test was created so that 4 out of the 8 questions are presented in a alternative format, and 4 out of the 8 questions are presented in a different color.

i.e. 2 questions original format and black color

2 questions original format and red color

2 questions alternative format and black color

2 questions alternative format and red color

I need to analyse:

1. the effect the question format has on the test score

2. the effect the question color has on the test score

3. any interaction effects of the variables

Which tests do i use??

I hope I've explained this OK and it makes sense

Thanks for any help!!
