Frequent Kernel Panic

In the last few months my Mid 2010 Macbook Pro 13" has been switching off/screen going black/screen going purple,red,green..... I wonder if anyone can decipher what may be happening from the report below? Whether it is hardware or software or what should be done?

Many thanks in advance.....
