|3/27/17 Caran d'Ache Luminance, Stillman & Birn Alpha sketchbook|
(If you missed the introduction to the series, please read that first for the methodology, as such, and my objective for these reviews.)
Luminance is the traditional colored pencil counterpart to my favorite water-soluble pencil, Museum Aquarelle, in the Caran d’Ache line – the very highest artist quality and including only hues with the highest levels of lightfastness. Like the Museum Aquarelles, the color range isn’t as wide as most colored pencil lines because the fugitive hues have been eliminated – no bright pinks, reds or purples. And also like the Museum line, Luminance pencils are so pricey that I’ve been acquiring them a few at a time. Thank goodness they are available open stock, which also enables me to get only the colors I really use.
One more similarity with the Museum Aquarelles is that their barrels are slightly larger than standard, so I’ve had a heck of time finding sharpeners that fit. I use the same Kum magnesium 2-hole sharpener that I use with the Museums or simply knife-sharpen them.
Swiss-made, these wax-based pencils are probably the softest colored pencils I have ever used, bar none. They apply almost like crayons, and after several layers, they start to take on a shiny, waxy surface, again like crayons. Because softness of application is one of my most valued qualities in colored pencils, Luminance pencils seem like they should easily be my favorite, just as the Museum Aquarelles are. But the more I use them, the more I think that softness isn’t necessarily the most important quality, at least with traditional colored pencils.
For one thing, they are so soft that they can’t retain a point, so defining small details is difficult, if not impossible. After multiple layers, Luminance layers start to feel like they are sliding off each other instead of building up. Although my apple sketch shows that the shaded areas blended well, coverage of the toothy Stillman & Birn Alpha paper was challenging. It could have used another layer or two, but I was trying to stay within the same time range to keep my test sketches comparable.
I don’t know if ability to erase easily is related to the ratio of pigment to filler, the softness of the core, or both (or something else entirely), but my erasing test shows that Luminance is much more difficult to erase compared to all the other pencils I’m reviewing.
There’s no doubt that these are gorgeous pencils, inside and out. The richness and depth of the hues is unbeatable. I love the brilliance of the red shown here, which I can’t seem to get with harder pencils unless I add more layers. The lightly varnished natural wood barrel is unpainted except for the end cap indicating the core color.
It’s just as well that the Luminance color range is limited, because I think these are best used in combination with a slightly harder pencil, both to extend the range of hues and to give detail when needed. I’m still experimenting, but I think I’ve had the best luck applying a layer or two of a harder pencil first for better coverage, then applying Luminance layers over them.
