Zyra's self-cast W seeds on her Haunted and Wildfire skins

This has been bugging me ever since the MYMU, and it's come to the point where I really want to talk to someone about it.

Why are the self-cast W seeds on Zyra's Haunted and Wildfire skins also purple??? I know that Riot wants them to be a different colour for clarity; so they can be distinguished from the passive seeds. This works fine on Zyra's classic skin (and SKT T1, I suppose), where both the reddish pink of the passive seeds and the purple of the W seeds fit within her vividly-coloured-tropical-jungle-flower theme.

However, for the Haunted and Wildfire skins, the purple seeds DON'T WORK OR FIT AT ALL. There is nothing purple on either skin and they just look really bad and out of place in the colour palette of each skin. Haunted now has a small gravestone that is entirely purple for its W seed. That just looks bad and it makes no sense. Wildfire has volcanic brimstone seeds that are purple. It just looks so out of place and I actually almost never pick my Haunted skin anymore because of it. Why couldn't her gravestones just have been a darker grey so they don't clash with everything else?

I have no idea if this is due to just copying the same colour overlay to all the skins, but could it be possible to alter the colour slightly? Please.
