Comment (by alwinramirus):
Yes I know that those are RGB values.
This was my guess as to what happens since the resulting rectangle is
drawn with the color (0, 206, 0) instead of (0, 245, 0) which is what
happens if you go RGB --BT.601--> YCbCr --BT.709--> RGB.
Looking at the code it seems like drawutils.c#L163-L165 converts the RGB
values to YCbCr with BT.601.
