Hi Lily,

You could have seen WLM logo variatinos with changed colors:
* blue logo of Wiki Loves Monuments Antarctica 2013 https://commons.wikimedia.org/wiki/File:Wiki_Loves_Monuments_Antarctica.svg
* green logo of Wiki takes oberes Murtal https://commons.wikimedia.org/wiki/File:Logo_Wiki_takes_Oberes_Murtal.svg
* yellow logo for the Wiki Loves Monuments Potsdam-Mittelmark https://commons.wikimedia.org/wiki/File:Logo_Wiki_Loves_Monuments_Potsdam-Mittelmark.svg

I guess this means that there is no problem with changing colors. Unless you end up being mistaken for Wiki Loves Monuments Antarctica :)

Best,
