Colour doesn't matter and just use a name brand fluid eg Castrol,Mobil etc
most std brake fluid has a boiling point of 270deg then it goes up to 310deg for racing .The main thing with brake fluid is to flush atleast once every year or earlier as the fluid gets contaminated from condensation etc .If you lift your cap off the brake master cylinder and put your finger in there check out the gunk build up, it happens.
The quickest way to change fluid is to bleed the old fluid out until the new fluid comes through.If you are picky the best thing to do is remove the reservoir and clean it out first.BUT it is always recommended to go to a brake specialist it costs about $70 to get a fluid flush.
