Creativity though constraint and continuity.
Before industrialisation, artists worked with ingredients they had access to, making paints, dyes, and inks in small batches using methods passed down through generations. Even with individual, artistic goals, artists had to work within the constraints of what was available.
While I have the benefit of a wide gamut of colours in almost any application, I decided to restrict myself to what previous generations of artists have relied on and in my own way, attach my thread to theirs like a backstrap loom, and see what else we can create from the same colours.
Sometimes, the choice of a cinnabar orange over a rosso corsa is intentional due to the cultural and period usage differences. Other times, I just like the vibrancy that a flood of cobalt blue adds over a moody indigo blue.
