Single post in Image errors!

As above, I'm not sure if this counts as an Image Error or a Sprite Discussion; it's not a new sprite for a new form/mon, but it's not a 'mistake' mistake so it might not be an error either... hopefully this is the right call? My quibble is with the outline for the bottom half of the albino Vileplume sprites, as pictured above. Since the bottom half of the outline is colored on the main sprites it makes sense, but it feels like the replacement color could be darker, because it seems to me to be way too pale compared to the black part of the outline, and that in turn makes it look incomplete or like the shadow is off. Compare this to the albino Ekans sprite: while the colored outline is pale there too, it's mostly at the top, so it's not as noticeable as with Vileplume.
