Environmental TechnologyCastin’ Craft Universal Transparent Resin Dye (1 oz | Red-Colored) Liquid Coloring Pigments for Polyester & Casting Epoxy | DIY Jewelry Making Concentrated Colorant Drops

Awesome Product! And does Not leave a smelly product!

This is a red but if mixed with resin with only a tiny amount it is a deep pink. The more you put the redder it gets but it goes fast as you don't get a lot to begin with. All resin dyes are expensive, it is just the way it is. But I don't use red often so it suits me.

I supposed if you are super familiar with casting you are probably aware that red is never really red, but I was unaware of that. This is red but it really turns into a dark pink not quite red, no matter how much you add. I needed it to cast a heart so it did not work out for me, but if you are looking for the darkest pink, this will achieve that.

It's quite nice. I got a nice deep garnet color with 3 drops per ounce of resin. It's perfectly clear, though you need to take your time mixing it to spread the dye evenly. Affordable too! I'm using this to make gems for a cosplay, and I was so happy to have the deep color come through on my first batch.

This brand of colors is great if that's the color you need. The seem to only sell the the primary colors. So, I tried mixing blue and yellow, and I got, grey. Not so good for blending colors.

Works fine. Takes a smallnamount

Even though I'm not a big fan of red, I have to say that this color when mixed properly is gorgeous. I'm never disappointed with Environmental Technology's product's

I add this to my automotive clearcoat prior to application for that "candy" effect, it works great!

Well it's red, mixes well with epoxy resin.
