Re Jonathan's suggestion of using absolute value, is there a gotcha in this part of the algorithm spec: >For all values of ω where r(ω) > 0, starting with the...

There's an odd behaviour that arises from taking the absolute value of the circle radii _in combination with_ normalizing the colour line, interpolating circles to the normalized colour line, and...

If the dotted lines aligned to the projected circle rather than the original circle, that would be diverging from the WHATWG createRadialGradient() algorithm spec.

I'm trying to update my HTML page, but encountering odd behaviour given that both ends of the colour line might require projection beyond [0,1]. Is there a build of either...

I've revised my HTML page to do what we discussed—extrapolate circles c0' and c1' from c0 and c1 for a colour line with begin stop offset < 0 or end...

Somewhat ironically, we began discussing a year and a half ago (#148) whether there needed to be colour stops within the [0,1] range, and [I asked](https://github.com/googlefonts/colr-gradients-spec/issues/148#issuecomment-853444877) whether we'd encounter any...

I wouldn't suggest any change affecting radial or (as we have in OT1.9.1 alpha) sweep gradients, neither of which have any such issues. But radial / two-point conical gradients are...

>Consider a simple color line with three stops... It may or may not be obvious to designers to craft a font in such a way that a ColorLine table is...

A different variant of (b) could be to treat stops outside [0,1] as D2D currently does: ignore them. It would still affect the pad/repeat/reflect patterns, so from your example comparing...
