Improving the color's meaning: The blue was set to #151189, which refers to November 15th, 1889; day of the Proclamation of the Brazilian Republic
from /r/vexillology Top comment: On the one hand, it's neat that a string that looks like it's relevant to the date produces a colour that works. On the other hand, I don't like this use of colour codes on quite a few levels. Firstly, I think the idea of precisely specifiying flag colours is emphasised way too much. There's nothing wrong with having an official standard, but flags don't naturally work on a level as precise as an RGB specification, and any truly publicly used flag will be around with a fair amount of variation. Secondly an RGB colour specification is fine for digital depictions of a flag, but not great in other contexts. You'd need to have some other standard for actual flags, if not printing on paper etc., so the symbolism wouldn't carry through. Thirdly, and this isn't really anything to do with flags, the idea of taking the hex string "11", which means the decimal number 17 (out of 256), as symbolising the decimal number 11. But people don't seem to agree with me on that...
