Paint dries darker?

Is it my imagination or does Winsor & Newton Artisan oils dry slightly darker in value? I'll go do a test but if anyone knows let me know. Thanks.

I've never noticed a difference but I've only used the W&N a few times. I'm interested in knowing the results of your test. Good to know if their is a value shift.

From W&N technical information about Artisans:
"As water is added some colours will lighten in tone. This is due to an emulsion being formed. The colour will return to its original hue as the water evaporates. This colour change is reduced by the use of mediums in addition to water. The colour remains wet and workable after the evaporation of the water, like a conventional oil colour. "

Essentially the emulsion can create a foaming effect that makes the color look lighter than it actually is. The less water you use, the less noticeable it is, and is more apparant in the darker values. This can happen with other brands also.

If it's bothersome to you, you might consider trying W&N's miscible thinner instead of water.

Thanks David. I hardly ever use water so I imagine my test with the oil medium will show little or no difference.

I've never noticed that with the W&N oils. My first thought was mixing with water might be the cause (thanks for the info, David.).
Tommy - have you noticed it with all or just certain colors?

I've used WN for yeaqrs and never noticed a difference. I never add water, though, i can't speak to that suggestion.

It's probably just my bias towards working too dark.
