Hello all,

This message is a simple plea to Jolla UI designers to keep into account that some of the Jolla users may be colour blind to some degree. In my case I have deficient ability to distinguish between red and green, especially the red, green, yellow and amber hues as emitted by LEDs. I see some intensity difference but that's all.

For example on the Jolla phone the orange and green which is used to indicate the "away" and "available" state of presence. To me they are just the same. Please consider changing the colour or better yet the shape (a cross, circle, arrow or wave).

Thanks for your attention!

I also suffer from a light kind of deuteranopia. Although I do not have problems with the status indicator in particular, I would rather go for symbols, like with N900, N9 and such. But for the colors, with traffic signals usually the red light has some yellow mixed in, while the green has blue mixed in.

@strongm Please convert your comment as an answer, so that could be voted as one possible solution to the question (at least I would)

I also prefer symbols as long as it is clear.

I'm not sure that changing the colours for everybody is necessarily a good idea - but having the ability to activate a user-selectable set of accessibility options (e.g. colour sets, font sizes, visual cues) seems like a worthy idea

Edit: As per simo's request, I have changed this comment to an answer.

Thanks I like this, fonts are indeed also an issue although most are okay for me maybe this could tie in somehow with ambiences?

PS: the N900 had a possibility to install an extension which enabled one to zoom contacts (they were to small for me eyesight).

This problem, legibility, has been the reason for this question: https://together.jolla.com/question/12830/ui-improved-legibility-css-file/

Unfortunately, there is no answer (by Jolla) yet. If there were such a central file we could play around with it, we may even be able to provide Jolla with suitable sets for different needs and requirements, so they could provide a neat set of UI elements in the Settings to select the pre-set of UI formatting settings that suits the individual user most.

But also in the default color scheme developers should keep in mind that red-green deficiency is the most common form of color blindness (see wikipedia), especially among men (probably the biggest part of Jolla users so far). So try to avoid using red and green as colors to indicate states for an item, even in the default scheme.

I don't think changing all colours for everybody is necessary, but including optional colorblind mode would be awesome. The LED, I think, is the most difficult part. Therefore, my idea is that LED could blink in patterns in colorblind mode (kinda like Morse code).
