Well, I have the large "purple' Kanger ProTank glass and it's a reddish purplish color. If I put clear
juice in it, it shows good color. If I put darker
juice in it, you lose color, but that's true with all of them. This IS clear glass. If I put red
juice in it, it shows more of a mauve color. The mini "purple" is more of a faint lavender. The large "blue" and the mini "blue" are a baby blue. Very pretty with clear juice. The large red shows red with clear or red juice. The mini red is a faint color. More pink.
The Davides both mini and large have a "dark" blue that is hard to see thru. The mini blue in some light looks almost dark purple. Bet it can me made purple with red juice! The large green is dark, but the mini is pale green. There is a large gold (not yellow), but no mini gold. The "purple" is very faint. More like a lavender. There is no large red, but a mini red shows well with clear or red juice.
I guess you wouldn't need colored glass if you could find the juice in colors you wanted to match your tips. I HAVE seen green juice, and I DO have blue juice besides the standard yellow, gold, brown, some red. Next having found them would be LIKING them!
