My example of when Double Dye doesn't make sense

[Rurulao]

For context
On the left are Lvl 60 White Mage job gear and the Virtue pvp version undyed
On the right are the same gears but the first dye is jet black
What bothers me is when i dyed the regular lvl 60, it also dyes the red lines while ironically, the pvp version only having one dye option, it does respect the lines being a different colored parts of the chest piece
