How to make purple colour with watercolours

History of purple colour

Brief history of purple colour

Tyrian purple color is a dye extracted from a murex shellfish. Purple was first innovated during the bronze age in Tyre. Royal families in that era reserved this color for the upper crust.

Here’s a story from Phoenician mythology,

Guess who got all the credits for discovering the purple color? A dog! Yeah, even I had the same reaction that you are having. Tyros, the mistress of Tyre’s patron god Melqart.

A couple and their dog were taking a walk on the beach. It came to the couple’s notice that after biting on a washed-up mollusk, the dog had stains of purple color on its mouth.

The reason for the purple color’s reputation is because purple color dyes were expensive in ancient times. It was valuable because the production process of the purple colour was difficult.

According to a historian, “Ten thousand shellfish (mollusk) would produce 1 gram of dyestuff.

The color didn’t become more widely available until the 1850s, after which the first synthetic dyes were produced.

The most common confusion – Violets and Purples? Are they the same?

NO it’s not. Here is a small excerpt (not too boring) from physics on the reason. “Violet is a light spectral color whereas purple is a combination of red/blue and violet light – That the humans perceive.”

Technical difference between purple and violet

Codes of colour which create purple colour

MUD – Warning! & narrowing down to further options with Cool reds and Warm blues.

To avoid creating a muddy colour avoid mixing green or yellow with red/blue.

Here is the reason!

• Green being the complementary color of Red, will neutralize it and create mud.

• Yellow will react with the blue part and create green. This green will again neutralize red and create mud.

Having said this, let’s carefully pick reds and blues that don’t have undertones of yellow or green.

I’m picking up the below colors. –

Cool Red – Carmine, Quin. rose and Rose madder, Warm blue – French ultramarine and a primary blue – Cobalt blue. Here are their combinations.

Here are the shades of purple that we can consider for various areas of a painting.

I’m using Carmine + French Ultramarine to create these swatches.

Shadow purple can replace shadow violet.
For the sky, a mid-tone of this mix would be apt.
The darkest shade for the darkest tone in a painting.

These choices are personal preferences and depend on the mood of the painting.
