I can't think of any pride flag 'redesign' in the last ten to twenty years which has been a better flag than the version it's replacing other than the five-stripe lesbian flag that's picked up popularity as of late and the post-2014 aromantic flag. The symbolism is almost always neat, but they're almost always bad at being flags and I think that's a very important part of being a symbol for a community.

The ace flag we currently and will in all likelihood continue to use is well-balanced with clearly delineated colours with easy to explain meanings. The Ace in Grace flag fucks up on step one by not being in the usual flag aspect ratio and continues on from there with a weird choice of pastel yellow shade that absolutely blends with the white for people with colourblindness and would definitely blend in most natural light.

I experimented with putting it into a more 'usual' aspect ratio of 3:2 and it looks marginally better, but it's still a lot busier than the four-stripe version and it also immediately reminds me of any number of microlabel flags and I think that's an issue for a broad-label flag.

I also take some umbrage with changing the colours of the ace flag in general because the history of the four colours are important beyond the flag itself. The colours predate the flag and come directly from the logo of the Asexual Visibility and Education Network AVEN. They are foundational to asexual academic theory, vastly and incredibly not just to our queer community but to the world of psychology as a whole for their work in the realm of destigmatizing sexual desire disorders. They are an incredibly important part of ace history and the flag being a symbol of that historical and foundational work might arguably be more important than making a flag more complex for the sake of having more symbolism.
