A slightly more in-depth paint review: Warcolours.

So, I found this company on CoolMiniOrNot's forums, and I was intigued.  Granted, this was mostly because they were, at the time, sending out free samples of their then-still in testing metallic copper paint, which is by far the best copper paint I've ever used.  So I bought a couple more paints, and, well, after a painting hiatus, your paints dry up and die, especially those in poor-quality bottles (and yet I still have some perfectly fine GW screw-top bottles, go figure)...So I needed more paint.  Got a fair selection of paints, a few metallics to bolster my stocks.

A few basics about Warcolours:
1.  Their paints have no-nonsense names.  A color (representing hue) and a number (representing lightness/darkness).  This is nice, because honestly, what even are Orkhide Shade or Cryx Bane Highlight?
2.  Their paints, along with the names, have a scale (looks like a cell signal) that lets you know approximately how opaque it is, which is very nice, especially when buying the paints.  You know exactly what to expect when buying these paints.

3.  They are cheap.  regular colors are 1.88 USD, metallics 2.43.  Shipping is reasonable, though it tends to take a while as it's coming from Cyprus.

4.  They come in dropper bottles.  Some love them, some hate them, I'm ambivalent.  Theirs are made of a little stiffer plastic than most, which some people don't like, but I do.  They also have childproof caps, which might sway opinions, might not.

Testing:

I started with a bit of scrap plasticard, which I primed.  Black, then went over half with white.  The white was Tamiya primer, which is super-fine and mostly intended for airbrushing over, so the first pass, you'll see the paint start to bead up a bit in places.  Not a real concern, though.

The primer coat is beat up, as it was a bit windy and it kind of fell onto the ground.  no problems, though, it's a simple test.

Going with 1 coat of each.  Left to right, I'm comparing Warcolours against Scale75, Vallejo, P3, and Games Workshop.  One caveat: the paints were brushed on, straight from the pot, and I have some OLD pots of paint (like 15 years or so), so bear that in mind.  Also, some paints behave differently when watered down: some need it, some respond poorly, etc.  This is by no means exhaustive or definitive.

Colors used (left to right):  Warcolours metallic black silver and metallic black gold, both 3/3 opacity; Scale75 black metal and necro gold.  WC blue-grey 3 (3/3 opacity), pink 3 (2/3 opacity), and copper beta tester (don't have the production line copper); Vallejo Model Color azure. Vallejo Game Color warlord purple, and Vallejo Model Air copper.  WC metallic antique gold, flesh 4 (3/3 opacity), and warm grey 5 (3/3 opacity); P3 rhulic gold, midlund flesh, bastion grey.  WC Nostalgia 1988 woodland greeen, orange 1 (3/3 opacity); GW snot green, bronzed flesh.

So far, we can see SOME differences.  Warcolours metallics seem to cover very well, but the opacity labeling doesn't seem to be too on.  Also, you can see some of the beading I was talking about.

2 coats:

Now we're getting somewhere.  Warcolours warm grey 5 and blue grey 3 are very nice.  The beta test copper is by far the shiniest thing on there.  Neither the pinks nor the fleshtones are covering too well, but that's, I suppose, to be expected.  The '88 green is making me sad, though.

3 coats.  Warcolours metallics are where it's at.  Scale75 has them beat on luster, save for the copper which is bright and metallic and pretty.  Warcolours flesh color is a bit pink for my tastes, and pink 3 is still very transparent, though to be fair only marginally more than its VGC counterpart.  Finally, the nostalgia '88 is disheartening at best.

Overall impressions:

Warcolours are a high average.  That is, their benchmarks are somewhere around those of Vallejo, which is pretty much the industry standard.  They handle closer to Reaper Master Series paints, though, slightly...squishy-feeling, maybe, on the palette.  The metallics are great, and from what I've used so far, very consistent.  P3 was going to be my new go-to metallic, but some of the pots I got were lumpy and inconsistent, others great.  Scale75 is wonderful but I'm not buying a set of 6 bottles every time I want another black metallic paint.  Other colors are more hit-or-miss,  I can't see much reason to use that woodland green, but otherwise, everything I have has a place in my repertoire of paints.

Pros:

Dry more slowly than most other paints

Dry pretty matte (similar to P3 paints)

Great selection of colors

Smooth, colors don't separate (only exception is the copper beta, and I'll accept separation for that level of pretty)

Names make perfect sense

Excellent range of metallics

Inexpensive

Cons:

Paints are hit-or-miss with coverage

Long shipping time to US

No ready-to-use fleshtone

Feel of the paints takes some getting used to

Overall, though, I'd give Warcolours paint approximately an 8/10.  A solid B grade.  A few areas of improvement, but overall great paints, well-priced, and with a quickly growing line of paints.  Not going to say you should replace your whole paint set with Warcolors, but if there's a gap in your collection, you could do a lot worse.  And at less than 2 bucks for a bottle of their basic paint, it's an affordable venture as well.

(yes, I'm an affiliate and I do get referral commission, this hasn't affected my review in any way.)

Edit: I just tried an impromptu durability test on my card.  Warcolours paints are pretty durable, at the very least, more so than the rather fragile Vallejo colors  This is the most unprofessional test I've done (took toothpick, needle, knife, ran across paint, the end), but hey, it's data.
