Hello dear Inkscapers,

I want to create tiled clones tracing the colours of a radial gradient with two colours of nearly similar H, S, L values (saturated green and yellow in this case).
In addition, the tiles should shrink according to the gradient (one colour meaning full size, the other no size). Because of the similar H, S and L values, I can't use these as input for appropriate sizing. Opacity doesn't work either, the colours are distorted (e.g. too much yellow) if I make one colour transparent.

I illustrated this in the following image:

Left: Input: colour. Output: colour, size.
Middle: Input: colour. Output: colour.
Right: Input: lightness. Output: size.

So I want to achieve a combination of the last two. I could group the correctly sized tiles and put the gradient over all of them, but I would prefer to have each tile in one colour. Can you think of a solution?

Just to inform you about the progress: I didn't manage to achieve exactly what I wanted, I used the gradient solution instead. Although it's clearly visible with larger dots and it's not so nice, I couldn't find another way (at least not without much manual work on every dot).

I should mention that I had some serious problems with the correct display of the gradients. The actual gradient center was far away from the corresponding gradient handle. I think it's related to this problem, although it also appeared in another group of objects, not involving circles. I solved this by turning the circle to be cloned to a path, unlink everything after cloning, removing all gradients (also manually in the XML editor because Vacuum Defs left many unused definitions) and trying to set them again from scratch.

So, it's only approximated to what I imagined and it was a hard way to get there, but the image is done. I hope this information will be useful to people who want to try something similar.
