Using your program’s colour picker, enter these same RGB
values, and change the logo to that colour.
The RGB colour displayed on your monitor may not necessarily match

probably due to the difference between how your monitor and printer
reproduce colour. Here, it is unimportant since your primary objective
is to print the required colour.
