How to create brown and how grey?

- Orange, blue (more blue) and white
- Brown
- Primary colour with complimentary colour
How to identify correct value and colour?
- Isolate colour from surrounding colours as they influence our perception.
- Use the cross-eye technique to retain Hue and Chroma
- Or cut out some wholes on a piece of paper in 2 different locations and use as compaing device. the paper around the whole will isolate the colour
- Determine value
- Use squinting technique. The eyes blur the scene a bit and one will see the original values. The eyes only desaturate the scene slightly.
"Beautiful Grey"
Painting and focusing on the depiction of exact colours can be very strenuous and as a variation painting in grey tones can be a nice challenge. Removing all colour and having simply a black and white value painting is boring to me though.
But I found an article about "beautiful grey" which has a great solution to retain the challenge of a colour painting by using grey tones with hints of any two complimentary colours to add tension and create engaging atmospheric artworks. This is something I would like to try out in one of my next digital paintings.
