Clear blue back in stock.

I need to make clear pricing now as bottles are a little cheaper. All so testing out new colours.
You definitely sent me the regular yellow. When I first opened the bottle, it looked blood red, and I thought to myself "WTF ?! Did he send me Red by accident ?" Then I put a couple drops in a glass

First impressions on the Yellow:
- You do need more dye to get your desired colour with this light of a dye. The test loop I put it in (about a one liter loop) took nearly 5 drops to get a good yellow colour out of it in high-light situations.

- If you have any light shining through the liquid from behind, it will look pink. Not quite sure why it refracts pink, but it does. Reminds me of Pink Lemonade when I had the light source behind the liquid.

- If you are using purely reflective lighting (the light source is on the same side of the reservoir/tubing as the viewer) then it has a distinct yellow colour. Adding more dye makes it a nice shade of orange, that resembles an almost-ripe orange (the fruit, in case you didn't catch on).

- When you first add this dye to your loop, make sure you give it time to mix and circulate through the loop. The colour increases in intensity as the last remaining dye that was floating on the surface of your res finally dissipates throughout the loop. Put in the recommended amount of dye first, and let the loop sit for 10 minutes or so before determining if it is too weak. I made the mistake of adding dye to the res and just agitating it, then putting more in, until I got the desired colour, and after 15 minutes the colour was MUCH darker and more solid than it was before.

Now, all I need is a night where I am not busy, and I will do some UV testing, and a bunch of pictures !
