arcColor: Color replication issue since 2.29.0

@marconett thanks for reaching out.

This certainly looks related to the color space used inside ThreeJS. It's typical of color mismatches with values in the middle (between 00 and FF), as the transfer function changes.

However, I cannot reproduce your case with the latest version of both this lib and ThreeJS itself.
I know ThreeJS has changed their internal color space logic a few versions back, which prompts me to ask which version of ThreeJS are you using, as this may play a factor.

My project is currently on three 0.150.1

[vasturiano]

@marconett that would be the reason why then. In a following version the color spaces were updated. 153 if I'm not mistaken.

mrdoob/three.js#26162

Thanks! For now I'm going to release with the older version but will keep in mind updating threejs later on.

I'd suggest updating the threejs peer dependency version.

[vasturiano]

@marconett yeah I thought about updating the peer dep version. But the fact is that the lib is actually fully compatible with older versions of ThreeJS, so it seemed to me it would be overly restrictive to do so. These are internal changes to the ThreeJS behaviour, which I would rather assume consumers are aware of.

But thanks for the good suggestion in any case. 👍
