Limited Palette Study: Phthalo Blue RS, Quin Coral, Gold Ochre

After my first limited palette study was on an unusual, almost secondary triad, I went more traditionally primary for one of my favorite subjects: sunset.

For my blue, I picked Phthalo Blue Red Shade, which is my favorite blue for the sky.

I then chose Gold Ochre for the yellow because it makes an intense but not garish sunshiney golden yellow, similar to my favorite sunset specialist Naples Yellow Deep; but it is more transparent so it makes darker blacks, which makes it more useful in a limited palette.

Of course my red was always going to be Quin Coral (PR209), my favorite sunset red, vibrant and warm.

In this exploration, I used Da Vinci Quin Red (PR209), Holbein Phthalo Blue Red Shade (PB15), and Winsor & Newton Gold Ochre (PY42).

Color Wheel

All three colors together get some interesting pinky browns, green-grays, shadow violets, and near-blacks.

The coral and gold together make a range of peach-to-grapefruit shades that I find delightful for sunset skies. The earthiness of the Gold Ochre keeps it from becoming too straightforwardly orange.

These really don’t make green very effectively at all, which is annoying for landscapes but great for skies.

Although orangey tinted, PR209 mixes like a pink in that it makes violets with blue. These aren’t the most vibrant violets (as one might expect since PBRS is slightly green-toned and PR209 is a warm pink), but they’re certainly not grays like PR255 or similar scarlets make with Phthalo Blue. These are nice sky violets.

Painting

Crow O’Clock. September 13, 2024. Saunders CP; PBRS, PR209, Gold Ochre.

This painting is a tribute to the sunset hour in Vancouver, when every evening, hundreds of crows fly overhead to their roost in Burnaby. I like a lot about this painting, including the paper towel lifted clouds and most of the crows – it’s just a shame that I did the worst with the one in the foreground!

I think these colors worked very well!

I knew PR209 would be great for the reds and it was. Love ya babe.

Gold Ochre was everything I wanted: warm, golden, and transparently mixable. I was pleasantly surprised by the deep blacks I was able to get for the crows, as I thought I’d have to add Payne’s Gray or similar. Nope! That’s just all three colors mixed.

As often in sunset paintings, I think I was a bit heavy-handed with the blue; I always think the upper sky should be dark to represent night coming on but in real life the sky remains quite light as long as the sun is up. I don’t know that this is necessarily a color issue, as I could just dilute it more. I like the violety blue from mixing some coral into the PBRS.

Conclusion

I knew this would probably work well because I have used PR209 and PBRS successfully in sunsets before. For the last year, I have been on a kick of using Naples Yellow Deep in sunsets, but its opacity can be tricky, so I was glad to confirm my suspicion that Gold Ochre can be substituted with all the same strengths:

  • Intense and bold, not too dull, glowing appearance in sjy
  • Yet also earthy, not too primary or fake looking as straight orange or yellow can be
  • Looks more orange in masstone (along the horizon) but dilutes to a delicate yellow
  • Does not easily go green with blue

Plus, being transparent, Gold Ochre can mix gorgeous dark blacks! I think Gold Ochre is a bit trickier to grade evenly, but I was happy with how it came out in this painting.

Overall, this triad worked extremely well for sunset! It’s one I’ll definitely return to.
