Prompt 7: Sunshine Jasper

Sunshine Jasper is an opaque yellow semiprecious stone, which means that this post is going to be about yellow graphics based on brown128.jpg. However, if one looks at the original, which is brown, and at the equivalent when the GRSites.com colour-wheel-rotation doohickey is applied, there is no obvious yellow version. However, have a look at the second graphic below. Because it is in muted tones, it appears an olive-brown colour. Its yellow base colour becomes clear, however, when the saturation of the colour is increased:



What the third graphic also shows is that, for the most part, monochrome yellow(ish) variants will tend to have the pattern marked out in shades of tan, brown, or grey. Furthermore, simply increasing the saturation accentuates any orange or green tints; so the result looks yellow & orange or yellow & olive. This certainly complicated my attempts to produce "solid" yellows!

Still, I did succeed in time; and you will find three examples in the first row. More heavily textured variants are in the rows below.



Note how brown tones increasingly shade the pattern as the variants become more complex. I added a few brown & yellow examples at the end of my first post (for Amber and Topaz); and here are some additional ones. Given the banded appearance of Sunshine Jasper, it seems appropriate.



Though slightly warmer than a true pale yellow (being based on more golden shades), I'm going to add a few variants in cream tones here as well.



A look at the photos of Sunshine Jasper shows that, while yellow is the dominant colour in the banding, some examples have a richer gold—approaching orange—among the stripes. While tawny and burnt orange shades were covered in the post on Amber and Topaz, many golden variants of brown128.jpg approach orange and/or have orange marking out the pattern. This happens because, when the saturation is increased, the muted (darker) areas of the pattern become reddish.

Take, for example, the deep gold of the first graphic here. I literally derived the second one from it just by increasing the saturation and contrast of the colours.



So let's have a look at some orange and orange & yellow variants.



And, since I added a selection of cream variants above, I'll finish with a few peach ones.
