The bordered flag of Poland in interpretation supported mostly by Polish wikipedians (more than 85% for).
White stripe is "white", and the red one is "crimson" (HTML names). Please note that this is not a normative version. The normative act of Polish law says it should look differently (see: Image:Flag of Poland.svg), but does not directly say what it should look like in w:RGB (sRGB).
