Help ID These Strings Please

[EdO.]

Bought this 2015 model Squier VM P Bass a couple weeks ago, basically a not too heavily played closet queen. Actually more an under-the-bed queen. No case, covered in crud and had probably been there for years but the setup on it was surprisingly spot on and once cleaned up plays very well. Has an old set of flats on it that I'm thinking from the colored ends (don't know the correct name for those) are D'Addario's. Blue sorta purplish silks on the ends. I've cleanrd the strings as much as possible, ton of dirt and crud but they have a nice 60"s thump to them. Trying to decide to leave them on or not, no telling how old they might be. Knowing what they are would help me decide on that. Bought the bass to use in a 60's tribute band so thumpy is good but need definition too. Anyway TIA for your input.

Thank you @michael_t, appreciate the ID. Thought thay might be what they are but I've never been a flats guy so wasn't sure.

Next question is whether to just leave them on or replace them with a new set oh Dunlop flatwounds I just purchased. I know a lot of folks leave their flats on until they disintegrate. And no telling how old they might be, could be 5 - 6 years old. They sound OK to me, old school thumpy to my ears but I need enough definition through the FOH system so it doesn't sound like mud out front. Bought the Dunlop flats after reading a bunch of posts based on reported reasonable tension and midrange response. Our sound man likes me to send him a flat/midrangy signal he can work with.

If anyone can comment on differences between the Chromes and the Dunlops that would be appreciated. Always been a roundwound player, this world of flats is a new (and interesting) experience for me and I'm happy to receive some schooling from the hive mind if anyone is willing. Again thanks @michael_t, appreciate the reply.
