Prompt 6: Amethyst

With Amethyst we come to purple variants—and a problem, since the word "purple" means different things to different people. I like the colours that, to me, are true purple, i.e. shades from indigo to (spectrum) violet, and perhaps those a little redder, such as grape; but I'm not fond of shades in the magenta range, which are also called "purple" by some, especially those in the field of Optics. However, the gemstone falls more in the former range; so I can focus on the hues I prefer with a clear conscience!

As before, I'd like to start with some essentially monochromatic ("solid") versions, in which the pattern is visible only as a texture. More heavily textured graphics are in the second and third row.



Of course, different shades of purple can also be combined with contiguous colours. Here, for example, is a slightly quieter set of "bluebell" variants:



And here are a more varied selection, including ones that combine purple with blue tones:



And purple with turquoise:



While this might seem to be all to say about purple variants, there is one particular (and rather unexpected) range of bicolours that turned up as a result of the use of the GRSites.com colour-wheel rotation software:



When rotated round the colour wheel, the muted areas (that, after much tweaking, produced the "feathery" bits in the earlier examples) have been altered to a brownish tint. On the other hand, applying a purple filter to the original graphic tints the muted areas to shades of lavender.



I think it's pretty clear how the graphics on each row are related to one another.

Sometimes when I was following one of these productive lines of tweaking, a whole family of variants would emerge. The examples below show how such variations can evolve. In fact, the top row here were all created in a single session in the order shown. A creamy tint emerged in the lighter sections of the graphic; and you can see in the lower row how, in later sessions, this was deepened to eventually produce a purple/brown/yellow tricolour:



On the other hand, along the way, I also got things like this:



A lurid looking thing, isn't it? (Not all the graphics I create look equally promising.) In this case, the filters and contrasts I applied really reduced the red: the brown became yellow; and some of the purple areas turned blue. Yet, in fact, I have used this variant (or a slightly darker version of it) as the background for a story about a fireworks celebration. So you never know.

Combinations of shades of purple with brown, beige, tan, gold, yellow, cream and/or ivory have also appeared through other methods of manipulating brown128.jpg. So, to finish this post, here are a mixed selection:
