Don't think black, look for the light ash shade and paint the tonal shapes. Remember, light is colour reflected and dark is colour absorbed, and so you paint with the colours you see in the tones. There will be more of the optically warm hues, yellow, orange, or red in the lightest tones, and more of the optically cooler tones of blue, blue-violet and blue-green in the darker shadows.
Take a look at the colour choices the master of light and shadow, Rembrandt, used when painting what we think of as black.

I went to look how I'd painted a black poodle in watercolours—I cheated—I hid her (the leading dog) in the grass, and left her all dark to contrast to the grasses and to not have her as a detailed focal point given she is near the edge of the watercolour painting. Just proves there isn't one way to do anything in art. The man's dark slacks gives a better idea of painting the tones being more important than what colour you use.

I am about to write a cozy mystery novel set in rural high country of Victoria similar to Daylesford and Hepburn Shire and the Mount Macedon and Mount Dandenongs.

You may be familiar with our former gallery at Buninyong, also in the Central Highlands of Victoria, and the paintings I've done of these areas.

I'll now enjoy writing about them.

And what of my art videos as I return to writing novels, for a long duration? I hope to write an extended series of cozy mysteries sit in this rural area I lave and now live.  My YouTube releases will be scaled bark to less frequent or shorter videos. My Patreon will extend more into offering support to both artists and authors. My tutorials shop setup will be further improve and I don't intend to stop my art journalling, I'll mainly share it with my Patreon.

I can recall, reluctantly, learning this poem in school. Although I loved poetry, this fell flat back then because I had no idea what this reverie business was.

Working through the photos I took with my new-second hand lens and I cannot believe the close up quality.

Get a head start the day and evening before. I make Sunday my preparation for the new week and pamper day making it easier to greet the new week. Instead of having a journal filled with jobs not completed from the previous week, I will have spent time over the weekend ticking off those things I have accomplished and set new goals, action plans, and to-do lists for the coming week.
I do a mini wardrobe sort and plan on Sunday making it faster and easier to keep appointments during the new week. 
The worst thing about Mondays for most people is having to rush or being tired due to strenuous activities on Sunday. Keep Sunday as a time to regroup your thoughts, plan your coming week, make exercise one of incidental activity as you tidy your surroundings and prepare for the week ahead, and strive to be in bad on time, or even a little earlier than usual as a catch up on any recent late nights.
