Look a bit closer at this photo. See the red sticky-uppy things? They're a carnivorous plant - Alpine Sundew (Drosera arcturi) - that feeds on insects that stick to the side hairs.
When I was taking this photo, I didn't see them because of my colour-blindness. I just liked the carpet of green of the Snow Cushion (Donatia novae-zelandiae) with it's little flowers turning from white through orange to brown...
A cineraria just about at its peak. They have really strong colours, these flowers.
On a side note, as someone who's a little red-green colour blind, I find that pink stands out for me much more than red. If I look right at something then I can tell it's red but otherwise it just...doesn't register. I don't have that problem with pink, it yells almost as loudly as orange does.
#a11y Do not use colour as your only indicator for information! 🚫
This restaurant uses red, green and brown coloured dots to display the dietary info of a meal. There is no chance of telling them apart if you are #ColourBlind. They are just too similar.
To solve this issue:
Use different icons or abbreviations (e.g. v+ for vegan, v for vegetarian)
Write a word instead of relying on an icon
Use colours that are more distinguishable and have good contrast in addition (!) to the text
I am not in any shape or form a UI/UX/designer type person, mainly because I have zero talent when it comes to creating attractive visual imagery.
But I do have to create a lot of diagrams in the course of my work, and I frequently use colour to distinguish between otherwise similar items which behave in different ways.
I have just been reminded by a colleague that not everyone has the ability to see the full range of colours.
If your work (or hobby) involves using colour to distinguish between things, especially if that distinction is important, do try to remember that fact. This linked web page is really, really helpful when it comes to choosing a fully accessible colour palette.
#accessibility at #comocamp: here is a simulation of what some people with #colourblindness see when you use coloured #stickynotes for #collaborativemodelling
Some of the colours are the same or very similar. See the third image for a set of stickies where the colours are distinguishable or the shape/size is different. You can also use symbols, or cut the sticky like @Steve_Read
1 in 12 men and 1 is 20 women have colour vision deficiency so you cannot rely on colour alone to communicate.
