Polyvine Acrylic Universal Colorant Yellow 50g / 1.76 fl oz.

Maybe I do not understand the purpose of this product... But after using the entire (!) black bottle on a little quart can of base paint, I got barely grayish results... Honestly, I would have been better off just adding some black color from my kids old finger-paint bottle. (Actually I did -- noticeably better!) So if your goal is to tint your paint -- this product is absolutely useless.

Good colerant, bright blue. I wish I had also bought a bottle of black to balance the brightness of the color, but this is a very good product.

Good product

did not do the job

Worked great for coloring grout.

Bought this to faux tea stain my walls. Worked good. A little bit went a long way. Came out beautiful.

Too small as size for anything

It's okay but not enough to actually color grey paint to black even though it says that its high concentrate.

Maybe there was something wrong with the tube I got. It squeezed out like it was jellified and it was very hard to mix it with anything (for instance water, white colourant, tile grout). When it was finally mixed in and to the shade of grey grout I wanted, found that it got a lot lighter when it dried. Few days later tried using normal black acrylic paint, went just as dark for a similar quantity, and stayed darker once it was dry. It was also much cheaper (£1.00 from Wilko for 75ml).

Used to tone down a red pigment to enable a more maroon colour and it has done what I needed it to do , not an exact match but close enough to do what I needed .

An Even colour but the quantity seems small for the price , it is a very rich and full colour and it will mix well in small amounts

Ideal for toning small amount of paints for blending and colour matching

Really like this, added to 2.5L Dulux White satinwood paint, came out a lovely pale but bright yellow, really stunning, have had lots of compliments as used it to paint tired kitchen cupboards. Very pleased with results.
