QoR® Watercolor Questions: Labeling and Lightfastness Ratings

  1. I enjoyed your open and honest posts. I will print them all and look forward to future ones. Just began using QOR watercolors and love them. They do handle differently; it seems that I can push the color around longer and the lifting is great even with staining colors. My tests show as good, or exceeding Winsor and Newton, in vibrancy. Thank you, Steve Gruber, California

    • Hi Steve –

      Thank you SO much for the warm words about our articles! That means a lot to us. And its also wonderful to know that we are holding up in all of your comparative testing. While we can talk all day long about what we put into the paints, hearing from artists directly about how we are meeting or exceeding expectations is especially gratifying. As always, if we can help further, just let us know!

  2. Hi, I am learning watercolor painting. I love this medium. I bought two sets of Qor watercolor tubes as my professional watercolors. I love them they are beautiful.
    i needed to refill my reds in my pallette. My two reds are pyrrol and pyrrol red light. When I opened my tubes again I have no red. The paint looks black. I squezzed some out and mixed with water and they are black/blue. Wierdest thing ever. I s this what they mean by fugitive color? Thank You Loretta Gentle

    • Hi Loretta – Thank you for the comment and letting us know. Fugitive definitely does not mean that a color should come out of their tube looking black! How very strange. The only thing we can think of is the possibility that the area near the neck of the tubes got contaminated with other colors. Do you think that is a possibility? In other words, that perhaps in squeezing out some color you accidently picked up some black or else something like a Phthalo Green or Blue, from the palette? If not, then we would definitely love to get the tubes back and send you out replacements as obviously Pyrrole Red should be, well, red! If you can, let us know your thoughts and if possible send us your address and even better, a picture of the tubes and the black color that you see when squeezing them. You can mail those to us at help@goldenpaints.com

  4. Excellent Info, this permanence is still scaring the hell out of me Sarah. In Digital we talk of Archival all the time. Yet here, impermanence seams to be the game of the day. 5 years ??? OMG

    • Hi Mark –

      Not sure what the 5 years is in reference to (let us know!) but we agree that lightfastness is a much needed area of research and testing and it can be scary when confronted with so much differing information. We promise that we will always share in a transparent way the testing we have done and know that if we ever discover that something is not as lightfast as we – or our customers – would expect, that we will take measures to address that and let people know. As we did, for example, with Hansa Yellow Medium:

      Hope that helps!

    • Hello Claudia,
      When a pigment we use in QoR is not rated for lightfastness by ASTM, or our own internal testing of that pigment’s lightfastness shows it has better lightfastness than the ASTM rating, we use “EX” and “GD”. “EX” stands for “Excellent” and is equivalent to ASTM Lightfastness I. “GD” stands for “Good” and is equivalent to ASTM Lightfastness II, or “Very Good.”
      Warm Regards,
      Cathy
