Colour data fields

I've recently switched from a Wahoo Roam v2, mainly because I wanted the larger colour screen as my eyes aren't getting any younger.

On the Roam the heart rate and gradient fields used to show colours according to HR zones and severity of gradient. The HR zones were particularly useful when climbing as an alert when over exerting myself..

Try as I might I can't seem to find colour data fields, so I have this large bright screen, just in black and white. Am I missing something? Or am I going to regret not waiting for the Wahoo Ace?

When shipped, the default data screen had a graphical heart rate field ghat was coloured, but as soon as I started editing the data fields the graphical data fields became a non-option. They're there in a list when editing but they are blank and if I choose one of them the data field just shows Timer. Is this right?
