Mix a Chromium Oxide Green Lookalike

Chromium Oxide Green (PG17) is an extremely opaque, lightly granulating single-pigment dull green. It’s a nice color for desert plants, but not the only nice color, and I haven’t found another use for it. So, I’ve been wondering if I want to remove it from my extended palette. I sometimes feel when I’m making color spotlights that I accidentally mix a hue. So let’s try mixing a hue on purpose.

My New Gouache Theory: Base Colors & Mixing Colors

I have a new gouache theory.

When I first posted my gouache observations and palette, I noted that some of my favorite watercolor pigments – the transparent, high-tinting ones in the phthalo and quinacridone families – don’t always make good gouache, because gouache is meant to be opaque. Phthalo Green gouache, for example, while thicker and less transparent than the corresponding watercolor, still isn’t opaque, and when you paint it out it can appear patchy. My favorite gouache colors were opaque pigments with more robust coverage: colors like Titanium White (PW6) and Hansa Yellow Light (PY3). 

I’ve come to realize, though, that there is still important value to those less-opaque colors, especially the ones with high tinting strength, because they can be great mixing colors. You just need to combine them with another color that has the desired opaque properties. You mix practically everything in gouache with at least a little white, anyway, so it’s not such a big deal that not every color has perfect coverage alone. 

I now mentally divide my gouache palette into two categories: base colors and mixing colors.

Artist Palette Profiles: Joyce Hicks

Joyce Hicks-inspired aspen tree landscape. September 5, 2023.

I recently enjoyed reading Joyce Hicks’ Painting Beautiful Watercolor Landscapes: Transform Ordinary Places into Extraordinary Scenes (2014, North Light Books) and painted out a palette inspired by the one she describes in the book. Of all the palettes I’ve explored, I think this might the best one I have enjoyed the most and most wanted to emulate in my own painting!

Mix Your Own Alizarin Crimson Hue

Alizarin Crimson is a notoriously beautiful and fugitive pigment. Many people now use Quinacridone Rose (PV19), Carmine (PR176), or other alternatives, but the color is often pinker and not as deep. So how can we mix a hue?

While I don’t have the original Alizarin Crimson (PR83) to compare to, I’m using Da Vinci Alizarin Crimson Quinacridone (PV19) as a point of comparison (upper left).

Here’s what I came up with.

Mixing Mauve for Watercolor Clouds

Violet, mauve, and gray cloud mixes with WN Phthalo Turquoise (PB16), top; DS Indanthrone Blue (PB60), bottom; DV Alizarin Crimson Quinacridone (PV19), left; DV Red Rose Deep (PV19), middle; DS Deep Scarlet (PR175), right.

Last time I looked at purple mixes, I fell most in love with the vibrant ones. Recently, though, in my efforts to make more subtle watercolor sky & sunset colors, I’ve been trying to find my favorite mixes for mauve, aka dull purple.

Artist Palette Profiles: Ron Ranson

I loved Ron Ranson On Skies (1996, Studio Vista), a book that mixes careful observation and teaching about cloud and sky natural history with practical painting techniques. Let’s see what colors Ranson used to paint skies!

The Paint Scoring List!

When deciding between paints, especially ones that I like equally well and that fill similar palette niches, I find it hard to juggle all the various factors to think about, many of which are not immediately obvious from first paintout: lightfastness, toxicity, drying shift, price series (cost), and tinting strength. That’s why I’ve come up with a needlessly complicated rating system!
