Bonus #1: Turquoise

When I did the prompts for Kyanite and Aquamarine, my focus was on hues and combinations from greenish shades of turquoise through to indigo. Only afterwards did I realize that I had not dealt with one fairly prolific colour combination: turquoise (or blue) with brown.

I have other plans for our last prompt, Opal. However, there are other semiprecious stones that weren't included in this year's Sunshine Challenge. This gives me an excuse for creating this bonus post.

If a turquoise filter is applied to the original graphic, brown128.jpg, the result is a rather dim brown and grey pattern, as in the second graphic below. However, increasing the saturation of the colours boosts the brown and turquoise tones. Further application of filters and contrast produces examples like the third graphic.



From there, it is easy to create the sort of variation found in the row below:
