Here in Ohio this Cactus has grown great and been developing nicely these past couple months.

There are only two small changes that I can think of:

1- the sun has been going down a couple hours earlier these past few weeks. I take it down from the window and put it under a grow light for just a couple hours a day. Nothing major.

2- the the temperature has been a little lower lately, but the plant has remained pretty dry so I didn't worry about it too much. Plus the temperature drop wasn't anything significant.

Any ideas or feel free to check out the picture. Thanks!

New spines are often a different color than mature ones. Your cactus looks great!

Is it possible the existing ones change color?

Probably

These are golden barrels.....who arent golden any more
Its likely an age thing. There was a ferocactus who did this as well

As the spines age, they will fade.

If the spines are wet their color can change as well - but usually not permanently.
It is what it is!
