Inconsistent graph colours since UI update.

Previous to this new version of the UI (browser verion), "My portfolio" showed up as a green line on the graph and the "chosen index" was blue, now the colours have been swapped! Yet when I'm out and about and view the Android app, My Portfolio is green and the chosen index is blue. Why the pointless and confusing change? Why not allow the user to choose their own graph colours? OR if the chosen index MUST now be green, then why not wait until you release and updated app before changing the web version? frustrating, it's the little things that make a good user experience.
