Well, my sheets of watercolour swatches have been in my window for four months now (if you want to see the originals, head to Part 1). Let’s see how they’re going…
Yellows and Yellow Earths
VERY slight fading noticeable in the diluted area of Lukas Permanent Yellow. Though it was visible to the naked eye, it is very difficult to discern in the scan.
Reds and Oranges
Noticeable fading for the two genuine Alizarin Crimson colours (pigment PR83). This pigment is known for being fugitive, so this is no real surprise. Though there is a Lukas colour called Alizarin Crimson, it uses a different pigment, which appears to be more lightfast. However the Sennelier and Winsor & Newton paints use PR83.
Violets, Pinks and Pale Skin Tones
No change to any colours.
Blues
No change to any colours.
Greens
No change to any colours.
Earths, Red Earths and Med-Dark Skin Tones
No change to any colours.
Shades
No change to any colours.
To see how the colours have stood up to 8 months in my window, head to Part 3 (link under construction).
