Switch v5 and v6 colors in graphics

[noahpierau]

In the graphics of the v5 and v6 block statistics, two different colors are used. Right now those colors are different for PoS and PoW.

• PoW: v5 is blue/purple & v6 is green.
• PoS: v5 is green & v6 is blue.

It makes more sense to me to give v5 the same color everywhere (blue) and v6 the same color everywhere (green). Especially on mobile it is confusing right now, since the block statistics graphics are visible by default:

green and orange indicates a success of the block/stake version update. this is decoupled from the barchart. when it comes to the charts, please keep in mind, that there could be more then two versions in the wild.

Yes, that is clearly visible.

This issue is about the v5 and v6 colors in the detail charts, which are different for PoW and PoS:

• PoW: v5 is blue/purple & v6 is green.
• PoS: v5 is green & v6 is blue.
