Looks nifty! I like it best with the text effect.

Color fill trail got a major update!

1. It no longer requires using the behind blend mode.

2. It only uses one file as opposed to two extra hidden operations.

3. It can now multi stroke with grow radius

4. It can control a hidden median that is meant to fix a bug relating to fill layers sharing previous colors. Sliding the median up removes the off color 1 pixel outline.

ALSO IT IS MANDATORY (AT LEAST FOR ME) to change the clipping setting from "adjust" to "clip" for this filters color layers to update in real time. I don't know why this is happening but this solves the problem of the filter not auto updating color fill layers.

REMEMBER TO CHANGE THE CLIPPING MODE TO CLIP!!!!!

I have two requests.

Adding gradient option and add 2 more color selections.

Nice effect! :bigthup

Oooh, having the basic rainbow's colors already set, something like this google screenshot below?
Nice idea (If @contrast_ does it, I would suggest to set the color, but the last 2 or 3 with full transparency by default)

I wish they had checkboxes as even when opacity is slid to 0 they are still active in memory slowing down the graph. I violated the rainbow by replacing orange with a light pink. If anyone nags me I will replace the pink with original orange.

Little Challenge (Python vs GEGL :mrgreen:

):

each color with adjustable grow and shift.
Take it easy: it's just a little exercise with fu_preview and gimpfu3. :hehe

i could make each one grow individually and add a individual bevel but it would be super long and confusing of a filter.

The ctrail.so shows "Latest commit 099f574 13 hours ago", but still 5 colors, did you put the good one? :hehe

It does not go beyond five colors and it has five colors enabled by default. It never went beyond that.

sorry you confused something. If I added a six color it would go even slower. I did in a non uploaded non official build months ago of that but it was extremely slow.

The only way I will add seven colors is if I figure out how to get a checkbox for each one.
It will be insanely slow if that is not done.

This is dated and has a known bug with median blur.
