 * Reason:The previous delist nom had issues, mainly with handling color breaks between lines. This version does not have that issue. The file size is over 10 times smaller, and the file format is SVG (preferred by many).
 * Articles this image appears in:Cognitive science, Color constancy

 * Comment I think there's a lot to like about your new version, but could you have a look at the shadow? It's a little odd. I mean, I know it's stylised, but it seems to have a slightly odd double-light-source look. The shadow is more subtly done in the PNG, which adds something to the illusion, as it's easy to almost not notice the shadow when looking over the two squares. The larger letters are a nice touch.

 * I see what you mean, and I completely agree. I've fixed the light-source issue and blended the shadow a bit better. Granted, it's not identical to the png. Of course, if wikipedia could render Gaussian blurs properly, I'd be much easier to match. If you believe the subltleness of the shadows is still an issue, I can spend more time adjusting them.

 * Question: The proposed image is not yet in any article - does it have to be, before it even can be nominated? If not, then I support replacing. --Janke | Talk 10:38, 12 December 2018 (UTC)
 * Janke No, it doesn't need to be. If the original is used in articles, than the closer (me) will change everyone to use the replacement image. Armbrust The Homunculus 14:12, 12 December 2018 (UTC)
 * I'm pulling this to WT:FPC. I do NOT want to derail a nom with off-topic discussion, but want to discuss this. Adam Cuerden (talk)Has about % of all FPs 05:00, 13 December 2018 (UTC)
 * OK, thanks for the answer, Replace. --Janke | Talk 15:29, 12 December 2018 (UTC)

 * Comment – it is recommended here (not required) that SVGs pass the W3C validator. I ran the check and got 2 errors, not sure how significant that is though. Bammesk (talk) 01:34, 14 December 2018 (UTC)
 * Actually, yes, it is in this case. I forgot to convert the "A" and "B" from text to path, which could cause rendering issues. Nonetheless, the problems are fixed, and now does pass the validator. Pbroks13 (talk) 04:43, 14 December 2018 (UTC)
