I fought the urge to do something safe and comfortable with the final spaces on the mandala and went with my gut instinct which was to add the “risky” color: red.
And I was right. It has added the complexity and zing that I wanted.
When viewed from far away it appears as almost dark blue, but the closer you move to it, the depth and complexity becomes apparent.
The final step will be to add back in the drawing lines with black ink.
