PO71 is a highly transparent orange.
Pigment Stats for PO71
Chemical composition: Diketo-pyrrolo pyrrole
Lightfastness: LFII
Toxicity: Non-toxic
Observations of DS Transparent Pyrrol Orange
Hue: A slightly red-of-center orange. That said, it should be noted that I bought the DS TPO in 2022. I am told that the older version was even more red and a bit more muted and earthy.
Graded Wash: Lovely, smooth gradients especially from the Schmincke. None of them get incredibly dark. Schmincke gets the least dark. All of them glaze to peach, with the Schmincke’s being the most yellow-toned (though still definitely peach and not yellow).
Opacity/Glaze: Very transparent with no visible color on the black line. In a glaze over itself, it becomes a dark pumpkin red-orange.
Comparison to Other Brands
Schmincke Horadam – Transparent Orange
Schmincke’s Transparent Orange (formerly called Translucent Orange) is the most bright and orangey of the set, neither reddish nor yellowish. It is much less red than the DS version. It dilutes to a crisp peach.
Winsor & Newton – Transparent Orange
I can’t tell if this is the same pigment or not. WN called it DPP (diketopyrrolopyrrole), but this is also the chemical that PO71 is made from. I suppose it must be slightly different or they’d just call it PO71, but it looks very similar to me.
In a direct head-to-head, you can see that the DS and WN are about the same hue, and both are a bit redder and more muted than the very bright and cheery Schmincke.
Qor – Transparent Pyrrole Orange
Qor has a very vibrant PO71, similar in hue to DS but a bit higher chroma. Like many Qor paints, I found it difficult to control or predict the cauliflowers.
MaimeriBlu – Pyrrole Orange
Lots of bubbles in the masstone, and a hue that veers a bit on the brown side. Very dispersive! It absolutely ran down the page.
Brand Comparison Table
| Brand | Pros | Cons |
|---|---|---|
| Daniel Smith | Large value range, deepest color, most muted, useful mixing, neutralizes Indanthrone Blue | Not as red as it used to be, too muted for some application (e.g. fall leaves); more suited to mixing than using on its own. |
| Winsor Newton | Large value range, flexibly use as muted or bold color, useful mixing and bold glazing | Jack of all trades and master of none, dries hard |
| Schmincke | Brightest chroma, true orange hue, gorgeous glazes, smooth gradient | Shallowest value range, prone to cauliflowering |
| Qor | Intensely pigmented, wide value range, useful mixer with similar hue to DS or WN | Not as “true orange” as Schmincke, prone to cauliflowering |
| MaimeriBlu | Smooth gradient | Bubbling in masstone, somewhat dull |
Palette Appearance
All of these PO71s, including Schmincke, look very red in the palette. Compare the appearance of WN Transparent Orange to Winsor Orange (Red Shade) in my palette; although TO is the lighter color, it’s darker and redder in the palette, and so I mixed them up every single time.
I guess that’s what you get with a transparent color: it will look extra dark on the palette because it’s like a bunch of transparent sheets overlaid, vs. an opaque color which just looks the way it will paint out.
Color Mixes – DS
Lemon Yellow (PY175)
Vibrant, fiery yellow-oranges!
Nickel Azo Yellow (PY150)
Compared to the Lemon Yellow mixes, these mixes are more subdued and goldenrod, but still very deep and intense.
Quinacridone Rose (PV19)
Range of reds from a coral similar to Quin Coral (mostly PV19), to a fire engine red (balanced mix), to red-oranges similar to Pyrrol Scarlet (more orange).
Quinacridone Fuchsia (PR202)
Bold deep reds, from cranberries through crimsons to scarlets; hues similar to Bordeaux, Alizarin Crimson, and Perylene Scarlet.
Indanthrone Blue (PB60)
You can make a dark solid black from this complementary pair!
Ultramarine Blue
Ultramarine’s mixes are similar to Indanthrone’s, but they don’t go as dark and are more granulating (hard to see the granulation on this paper). The mostly-TPO mix yields a surprisingly “bright” brown.
Cobalt Blue
A similar range of browns and grays with Cobalt Blue. You can see the granulation better on this paper, especially in the diluted mixes in which Cobalt Blue flecks float over the orange/brown shades. The slight muting in the mostly-blue, diluted mix gives me a Cerulean feel.
Phthalo Green Blue Shade
The TPO mutes and warms the Phthalo Green, creating greens that are still bright and bold but a little more naturalistic and suitable for landscape colors.
Viridian
I found these mixes surprising. The hues are similar to the Phthalo Green mix, but the qualities are totally different. With a bit of green, you get tan! Cool, lighter browns are hard to mix, so this is a good one to remember. With more green, there is this cool copper-with-patina look, especially given the floating granulation of the Viridian.
Colors Mixes – Winsor & Newton
Indanthrone Blue
Indigo
I don’t like these as much as the Indanthrone Blue ones. But the black is also quite even here.
What Others Say
This orange is a bit more mellow than its abrasive cousin, PO73, and has more depth than the rather popular Halloween-looking orange made from PO62. If you’ve been around the channel for awhile, you may have heard me sing this color’s praises before, especially the Daniel Smith version that was much deeper and darker in color than the other brands I’ve tried. Nearly red in color, this beautiful color was amazing for mixing the perfect blacks when combined with Phthalo Blue and has been a staple on my palette for many years. However, starting a year or so back [from 2019] I had several viewers and fellow artists say that they weren’t having much luck neutralizing this color like I seem to in my videos. I was rather confused, but recently picked up a new tube to see what all the fuss was about, and sadly, I can confirm that what was once a very unique version of this color is no more.
Denise Soden, Color Spotlight: Transparent Pyrrol Orange
Check out Denise’s video above to see a comparison of the old and new Daniel Smith colors for yourself. Note that when most artists online pre-2018 praise this color, it’s the former Daniel Smith version (this includes Liz Steel, Jane Blundell etc.)
About Schmincke’s much lighter/orangey version, which was the first on the market:
At an art fair I came across a colour I would now be lost without -if you haven’t tried Schminke Translucent Orange you are really missing out on something very wonderful! When diluted, it is really transparent, glowingly vibrant and works well with many other shades as a contrast.
Jean Haines, quoted by Peter Ward
My Review
I’ve gone back and forth on this one, since it’s easy to mix oranges, but this is a fabulous mixer. It combines with colors I already have on my palette anyway to make a wide range of other colors and lets me cut other colors that I’m “so-so” on.
- With magenta (e.g. Quinacridone Magenta (PR122) or Quinacridone Rose (PV19) variants), it makes fire engine red or red-orange.
- With any bold yellow (e.g. Pure Yellow (PY154)), it makes a bold yellow-orange.
- It neutralizes blues to grays. With Indanthrone Blue (PB60), it makes a bold black (especially the DS version).
- It makes greens look more muted and “natural” (though I prefer granulating Transparent Red Oxide for this job).
With that said, this isn’t the first orange I’d put on my palette if I were going minimalist; I’d grab an earth orange (such as Burnt Sienna, Transparent Red Oxide, etc.) before this one. Brighter oranges can have an unnatural undertone in mixes and are too easy to veer into mud; earth oranges mix a wider range of gentle, pleasant browns.
Favorite version: It depends what you want it for!
I would tend toward Schmincke if your use case is bright colors, e.g. fall leaves and florals. The main competition for this use case is probably Quinacridone Coral, which also makes lovely warm glazes and bright orange mixes.
I would tend toward Daniel Smith or Winsor Newton if your use case is mixing, e.g. neutralizing violet-blues or mixing more intense red/scarlet/earth colors. The main competition for this use case would be maroon or earth orange.
