Help Me Pick A Strain

Hi I'm doing my first indoor grow and I want to start off with some decent seeds, I'm looking for a strain where i get some purple bud or some blue bud and I have a somewhat small budget, could someone reccomend a strain from attitude or nirvana i will be growing 4 plants about 4 foot tall under CFL's and i want to keep the prices of the seeds under $40 USD

Thank You!

Try bubblecious snow white or aurora indica from nirvana there all good...
