This image of simple geometry is ineligible for copyright and therefore in the public domain, because it consists entirely of information that is common property and contains no original authorship.
The official Procion specifications are meant for manufacturing and dying the flag and can't really be applied directly to digital format as the resulting colour could vary depending on the material and amount of dye used etc. Until the Bangladeshi officials regulate the digital colour standards the best way is to approximate the file's colours on how the flag looks in physical form, which the dark green and red version does the best.
