An issue I have with Liquify is the colours of the gimmicks don’t quite match any silver or gold rings other than those supplied. The red gimmick also isn’t ketchup coloured. Has anyone tried customising the silicon gimmicks to change the colour, or does anyone have any suggestions on how best to do this?

I have tried to dye or change the color. but I think if you use a ring/whatever that's close in color, it won't matter. You're "liquefying" a solid object, who's to say if it would be the exact color. Just a thought.

Yes, as Nike used to say, Just Do It!

Muggles don't have enough computing power in that moment to consider saturation and hue, never mind that you've got a gimmick that looks like liquid/molten objects. If you act like/believe it to be, people will follow you and join the journey. Leave the doubts behind and just perform the effect.

I haven't tried customizing myself, but for the same reason, I feel like I will likely not get much use out of the red or green ones.

However I think the Silver, Gold, Black, White, Chocolate, and Caramel, are more than close enough for most uses.

That said, I am considering trying to add some specular (white) highlights on the Silver one to see if that works and looks ok in motion.
