Wrong logo, it should be a square one
If requester is right regarding the logo's background (it has to be white), the submitted logo is still incorrect because the most used logo is square and not a circle one.
One can check coingecko (https://www.coingecko.com/en/coins/karma-dao), Cmc (https://coinmarketcap.com/currencies/karma-dao/) or Roll (https://app.tryroll.com/tokens/KARMA).
All those sites are using the square logo.
So, according to rules, requester should make a fresh submission with the square logo and this submission should be denied.
