<P> Because of the use of the word' cyan' (Greek: κυανός, Kyanos), which can also mean' blue' in Greek, the exact shade of blue remains ambiguous . Although it implies the use of a light shade of blue, such as on the flag of the United Nations, the colours of the Greek flag tend to be darker, especially during the dictatorship and in recent years, with the exception of the years of the rule of King Otto, when a very light shade of blue was used . Consequently, the shade of blue is largely left to the flagmakers to decide, as shown in the table below . </P> <Table> <Tr> <Th> Official colour (White) </Th> <Th> Official colour (Blue) </Th> <Th> Colour system </Th> <Th> Source </Th> <Th> Year </Th> <Th> URL </Th> </Tr> <Tr> <Td> White </Td> <Td> 286 C </Td> <Td> Pantone </Td> <Td> Album des Pavillons </Td> <Td> 2000 </Td> <Td> </Td> </Tr> <Tr> <Td> 0% - 0% - 0% - 0% </Td> <Td> 100% - 60% - 0% - 5% </Td> <Td> CMYK </Td> <Td> Album des Pavillons </Td> <Td> 2000 </Td> <Td> </Td> </Tr> <Tr> <Td> White </Td> <Td> 285 </Td> <Td> Pantone </Td> <Td> 2008 Summer Olympics Flag Manual </Td> <Td> 2008 </Td> <Td> </Td> </Tr> <Tr> <Td> White </Td> <Td> Reflex Blue </Td> <Td> Pantone </Td> <Td> 2012 Summer Olympics Flag Manual </Td> <Td> 2012 </Td> <Td> </Td> </Tr> </Table> <Tr> <Th> Official colour (White) </Th> <Th> Official colour (Blue) </Th> <Th> Colour system </Th> <Th> Source </Th> <Th> Year </Th> <Th> URL </Th> </Tr> <Tr> <Td> White </Td> <Td> 286 C </Td> <Td> Pantone </Td> <Td> Album des Pavillons </Td> <Td> 2000 </Td> <Td> </Td> </Tr>
