Betta Changing Colour?

[f1sh]

I got my betta a week and a bit ago and he seems to be changing colour. He was a really bright blue colour all over, and quite a bit of his fins still are.. but the top half of his fins have now turned red.. and his body seems to be going a more purply colour.. is this normal? xx

yes please post pics to make sure it isn't anything bad..the red could be a bad sign, otherwise he may just still be young and growing his colors in. pics please!
