I'm a colourblind player, and I'm having issues discerning between Skarner's Spires and Redemption

Particularly Guardian of the Sands Skarner. The light blue is very similar to Redemption's colouration, and the particle effect is similar as well - a smaller circle within a larger circle, slowly moving towards the centre. I found it confusing when fighting around his spires - moving towards a recently captured spire thinking it's redemption, only to realize it was a spire, and potentially getting caught out. It's a minor issue, but I would really appreciate it if Riot could make it slightly more clear.
