crystallisation

Hi everyone. I had a problem with color of my 4mmc crystals. Crystals become BROWN color. Does anyone have a solution of this problem ?

For example, if it has a brown, orange color... (that is, dark colors) does it mean that it is impure and if the crystals are transparent, does it mean that they are pure or does the color not define the purity of a drug?

In order to make crystals do you drop the ph of the greebase to ph 3 or ph 6? Ive read different accounts on here. Usually to make mdma i lower the ph to 3 then bring the solution to 130c. So wondering if methbase is the same.
