Rebecca, thanks for the helpful examples! You’re absolutely right about value being more important than color (hue). I’ve seen your explanation some time ago and started working accordingly, as you can see in the examples before I started with the Waterhouse drawings and this painting.
However, there is a slight problem with this approach if the goal is to produce a painting that has a (neo)classical look, like - say - Carravaggio, Frans Hals or Waterhouse for that matter. I’ve tried to produce such digital paintings with a black/midgrey/white grisaille and failed. It looks too metallic, too digital. So I turned to the traditional oil painters for advice.
I know for a fact that Hals (and Rubens!) did his underpaintings in the way Caravaggio did, with a slight difference: for the ground he used a mix of ivory black- which is not quite black but very dark brown/lead (flake) white, which is not true white but a very pale cream and a spot of burnt sienna, giving the mix a pinkish tone which is so often found in Baroque underpaintings. The grisaille was then painted with midrange greys, never going beyond midgrey. The reason is simple if you have ever painted in oil: coloured glazings darken the painting, not to mention that a single glazing over a very dark grey has no effect whatsoever.
Caravaggio painted with only three or four pigments over such a low keyed grisaille! Yet his painting have an extraordinairy brilliance and livelyness.
Here is a beautiful workshop (oil) exploring this way of painting, hosted by an oilpainter with a mileage of 20,30 years or so.

Recently oil painters have begun to explore the digital oil paints and while there is still a lot of discussing and experimenting, it appears that digital “oilpaint” behaves indeed in a somewhat similar way to real oilpaint, but not quite. (They’re still looking for the turpentine and linseed, lol!, but hey! it dries a LOT faster)
The smooth blending you did is unsuited for an digital imitation of a traditional oilpainting. Even with carefull blending, there is still a lot of variety in the shades of grey in an oilpainting. One of the reasons why I think digital paintings often look slightly metallic and/or hyperrealistic, is because of this smooth blending. It doesn’t exsist in traditional art. So I’d like to try it the way as described in the workshop above blendng with brush strokes only, and mixing the paint in the process. This is just as tedious and time consuming as in real oil (for real fun an a guaranteed headache: try copying a Van Gogh or Seurat).
This is not to say that your method is wrong. It isn’t, but it’s not the right one for what I’m trying to achieve (a painting in the Waterhouse style, who probably also used the Caravaggio method, certainly in his early work).
As for the color: yes, you’re right, I should stick to greyscale for the moment, but have a heart. We’re in the dark, grey, rainy days before Christmas and I am afraid if I don’t do a little colour now and then, I’ll go berserk and spam the entire board with bright Chrismassy thingies.:twisted:
