White

There was a certain feeling Alex got from the monolith as it tested his talent. The pulsing energy had been getting progressively stronger, but his body was simply too strong to care about it during the earlier phase.

But now, as it got close to becoming blue, the energy was stronger and Alex felt the strain of it in his body.

Weirdly, while the strain did hurt Alex both physically and mentally, the attack itself didn't seem to be on either of those two. The attack, if there was one, was somewhere else, and the result only appeared as a strain on his body. 

Was it targeting his talent? Whatever the case, it was still at a level where Alex could handle it rather easily.

Alex waited as the monolith burned bright blue. The redness in the purple was all but gone now and only the blue remained.

When blue shined brightly, Alex could hear gasps from the group of elders who were until then talking among themselves.
