You can experiment with Bitfeed to watch blocks get built in real time

There’s a toggle switch in the settings where you can set color based on fee rate.

I believe that MemPool space has an arrangement with Bitfeed to incorporate their colorful block display into MemPool.

Thanks! This is helpful for my everyday life too! I wish I had known this earlier. Haha

I believe the color is the fee rate so varying levels of fee rate changes the colors of each little block.
