[B]consistency – uniformity of consistency; smoothness
[/quote]Yes, we have this now for oils. Makes sense that it would be there for Acrylics, too.

drying time
[/quote]I’m no Acrylic expert, so bear with me. All acrylic paints are (supposedly) fast drying (as compared to oils, I mean). Is “drying time” something that varies from one color to the next, within a line of paints, or is this something we can evaluate an entire line of paints on? i.e. Liquitex dries faster than Holbein.

transparency/opaqueness (as applies to color)
[/quote]With oils, we split this into two questions – one asking to rate the opaque covering power, and the other to rate the transparent qualities. I assume we could do the same here?

lightfastness
[/B]doesn’t lightfastness (and permanence) vary from one color to the next? If so, it would be tough to ask this question. Of course, if it is possible to evaluate an entire brand or line of paints with regard to lightfastness, this would be a good one.
Again, I’m no acrylic expert, so feel free to “trout slap” me if I’m asking silly things.
Cheers.

Lightfastness varies from one color to the next.
However one might be able to evaluate this quality perhaps, as it pertains to “artist grade” vs. “student grade” paints within each brand of paint.I don’t want to give the impression that I am an expert regarding acrylic paints, because I am not.
What I know about acrylic paints is based on my experience of painting with them for approximately 20 years.

[B]
Drying time does vary from color to color within a line of paints.
However when I switched from using Winsor & Newton to “Golden” I was certain that Golden paints didn’t dry as quickly as W&N.
[/quote]Yes, but is it all relative with acrylics? I mean, if some brands take a really long time to dry, and others don’t, I’d say this is something we can ask a reviewer to grade. If all acrylics dry fast, but some slightly faster than others, I’m not sure this will be very valuable.

I think it would be sufficient to rate the opacity of colors. I think that knowledge of opacity of colors is more desirable for acrylic painters but I can only really speak for myself.
Also, if opacity is excellent for a particular color, this color is obviously not transparent.
I don’t think (in fact I am quite certain) that opacity of colors does not vary from one brand of paint to another. [/B]Here I go “assuming” again.
I was under the assumption that, like oils, certain colors are opaque, and some are more transparent. If this isn’t the case, then a single question would work. Perhaps you can give me an example of the question we would ask, then the 5 possible answers.Cheers.

[/quote]As the student and professional paints are in separate categories, does this make sense? Remember, the detailed product comparison only happens within the same category, so you can’t really compare student paints to professional paints.

[/B]Hey, that’s 20 years more than I’ve worked with them – lol.
Cheers.

I agree with you – all acrylic paints dry fast.

I agree with you again.

You are correct in your assumption.
I second the consistency bit as this varies so much in acrylics – some brands are very fluid, others very stiff. And different artists prefer different types.
I’m a fluid girl myself and would rather buy a fluid consistency brand then add medium.Color changes in acrylics are also common when using mediums – so maybe a way of grading colour consistency when medium is added? Some brands are much better at “holding” the colour value with medium. That would be a trait of the mediums rather than the paints, btw, from my experience. Grading would be something like ‘no colour change’ to ‘large change in opacity’ when medium is added per the manufacturer’s instructions.

I have a thought about the following:
Pigment/Color Quality
I recommend instead of color quality, you spell out the color quality I think you are referring to which is “lightfastness”.
So, how about:
Pigment/lightfastness
Hi,
Lightfastness connotes permanence.
This is a direct quote from artlex.com:lightfast – Having the ability to resist fading on long exposure to sunlight. Denotes permanence when applied to pigment. The opposite quality is called fugitive.
