Graphic suggestion: Daily stress and body battery

For stress and body battery depictions on the app, lines switch from blue to orange at specific levels.

I propose changing the graphic so that there is a yellow tip on top of the blue line, as it approaches the cut-off point to turning blue.

Perhaps there might also be a point beyond in which the blue line has a yellow and orange tip. 

Not to confuse information, but to suggest the gradual change and make it appear to be less dramatic. 

There could be a more colorful "grey" area between resting and stress. Completely low and high stress would still be blue and orange.

Perhaps it might only be applied over a +2 -2 range of the point of the current graphic shift. (designers can game out the specifics) 

This small change in the display probably will not impress long-time users but new users might have an appreciate it. 

I say this because I found the blue / orange shift to be visually dramatic, when I first started using the Garmin app.

Thanks! I hope somebody likes the idea!
