I had the [Close Gap] set high so it would produce gaps on purpose, so I could demo the [Close Fill] tool. Setting [Close Gap] to a low number will result in no gaps most of the time, it works the same in TVP, the lower the number, the better the result. Retas will add AA to the lines when they are rendered in CoreRetas like Harmony and Harlequin does so AA is perfectly managed. Please note in the video I used a very low resolution image so I could show how pixels interact with the [Fill] tool. Here is an example of resolution differences when working in PaintMan.
I made a couple comparison videos where I painted the same image using TVP and Retas PaintMan to test the speed. TVP had some problems with leaving a lot of unfilled areas, I spent a good hour testing tolerance levels before I started painting. Elodie mentioned that CTG solves this problem and it sure does, I could have used it in the video especially for the method I went with, but in the original topic I was also comparing price as it was an issue, so TVP Pro features were out. TVP Pro is over $1000+ compared to Retas Studio's $160+, so it wouldn't have been fair to the OP. Worth it; but no good if it is out of budget. Note the method I'm using isn't what Retas PaintMan does, I'm just creating an alpha shape out of the blue, red and green lines and dealing with them separately, locking transparency and filling those shapes, that way the line was absorbed rather than used as a reference, but it's a lot slower.
It's actually quite similar to what aldehyde did in theory, however he used his final intended color for the separation line whereas mine was blue, indicating shadow to a separate color assistant.

Retas PaintMan has a tool called the [Extender] tool which works similarly to the [Smudge] tool found in Photoshop where it drags color, but only over unfilled gaps, it's pretty smart, it means you don't need to pick a color manually from a palette or eyedropper, just click and drag on the frame. If you watch the video, I use it at the end.
I really like CTG but it's too restrictive for high detailed anime stuff or even simple color boundaries as shown in this thread, the normal [Fill Tool] is better for that, it just needs that [Include Color Line] feature and [Extender] tool from Retas PaintMan and it would be perfect, I could ditch Retas altogether.
