Hi steemians and artist of this community.Its a pleasure to have you here. I would like to share this piece of art work with you and it should be worth a thousand words to your perception.
This is a technique in illustration of derivation of secondary an tertiary colors.
Red + Blue = Violet
🟥 + 🟦. =. 🟪

Yellow + Blue = Green.
🟨. + 🟦. =. 🟩

Red, Blue and Yellow are primary colors while Green and Violet are Secondary colors derived from primary colors.
Thanks for stopping by, I hope you liked it.And could you tell me the secondary color derived from mixing Red and Yellow? 🟥+🟨= ❔
