Red colour should be reserved for error states

[glynhudson]

I've been in communication with @chris1howell and we both feel that red colour in the UI should be reserved for error states.

This is related to #13, I think the colours in the UI should match the colours on the RGB LCD where possible i.e sleeping / disabled is a purple colour. Although I'm not too fussed about the actual colour used, but I definitely think red should not be used unless there's an error.

Currently, red is used in a number of places in the UI. I propose changing all instances of red to be purple, or dark blue to match other UI elements?

Red is kind of of convention for stop/power off/disabling/Cancel...

Error state are also marked in red as they are supposed to have switched the evse to a disabled state too.

Using purple for such buttons, disabled status tags doesn't make much sense in a UX perspective.

What could be an other way?

There is a lot of information on the subject, especially if you look at SCADA systems. This is a great resource linked below.

Alarm color should be bright and not used for anything else. Grey may be a good choose for disable.

we are talking about UX conventions for main users not sure industrial conventions are really suited here.

But I get the point, will check how it goes with greyed out, but you loose a lot of emphasis

@chris1howell @glynhudson I've removed the red color for everything than errors. It's a bit less appealing but this will fit for now. I'll have to introduce a new color in the palette somewhere else, dunno yet. It's pushed on master, new builds are ok

[glynhudson]

Thanks, I've just flashed the new build. That's great, I like it. I think it looks more elegant, but importantly it will clearly highlight when there is an error. Having clear error reporting is very important for an EVSE.

I've added some visibility to errors, now monitoring nav button goes red if it gets error and default jump to Security tab :
