What do the different colours mean on iphone se menus - where are they explained?

I have tried to view the manual but can not find out

Red, Green , Blue, Cyan must all have a system wide meaning but I can not find it. Even when I 'go into' a red menu item it still stays red after I exit, so it does not mean important/urgent but it must mean something I assume,

and what happens to the red/green colour blind problem (10% of males)- how can I change the colours for that ?

Good heavens - you are implying that each app has different meanings in menus for the colour they use, there is no standard on an apple phones!

If that is the case I will assume they are just trying to make things pretty and not help the users - pure frustration in buying an inconsistent interface - as you guess I am unimpressed with the MMI

Thank you for your concern in replying

Thank you , but there is no search faculty on the web page in chrome and it is not possible to download a PC version of the manual.

There is little point in me trying to read it on an iphone when I do not know how to use the phone!!

Hope this will help

'menus' to me are things that react when you prod them - ie active hotspots

this is a multicoloured example...

and here is mine!

Thanks for the suggestion - so I tried the MicrosoftEdge browser which gave the same results

I even tried it from the iphone and again there is no search areas next to the manual

I am DOOMED !!

Thank you - I should have been able to find this in the manual, but it is not searchable on my PC as we can not download it!
