Current color of Keli Mutu lakes?

I was in Keli Mutu in 1994. At that time, the lakes were colored as follows:

Tiwa Ata Polo (TAP – the first one on your right as you walk to the summit and see the pair of lakes that are next to each other) – dark green with some upwelling.

Tiwu Nu Murikoohi Fah (TiN - the one next to TAP) – bright turquoise with a fair amount of yellow sulfur floating on the surface.

Tiwu Ata Mbupa (TAM – the one that is a little separated from the others) – the color of black coffee, with just a hint of reddish overtones.

Does anyone know what colors they are now? Also, it is my impression that TIN is always turquoise. Is anyone aware of it ever being a different color?

It’s not the best image, but this google maps link will show you the lakes:

Tiwi Ata Mbupu at least appears to still be bright turquoise!
