Some people have a disability detecting colours

[William Overington]

Following on from my post in the following thread,

https://forum.affinity.serif.com/index.php?/topic/154579-christmas-cards-2021/

I have received a kindly-worded private message that mentions an intereting web page that allows someone to check his or her own artwork as to how it would appear to people who have each of a number of disabilities detecting colours.

As I have found the resource helpful, here is a link.

Good evening @William Overington (at least in my neck of the woods). You can easily simulate different forms of color blindness without ever leaving Affinity Photo. Simply add a LUT at the top of the Layers stack, and set the LUT to one of AP’s presets - Deuteranopia or Protanopia (for red-green deficiency) or Tritanopia (for blue-yellow deficiency). No need to travel to a separate web site!

See for example also:

... under the softproofing points there ...

Quote

Color blindness settings in Affinity are located among the built-in LUT adjustment layers. The LUTs help you visualize colors as seen by three types of dichromats: protanopes, deuteranopes, and tritanopes.

@William Overington As you have raised the issue, the choice of colour in your Christmas card causes a sort of strobing effect that would induce a headache if looked at for too long. I appreciate the sentiment in the card, but the colours are all wrong.

Hello Ali

Actually it was not me who raised the issue initially, it was someone who sent me a private message about it.

Regarding the sort of strobing effect that you observe, what colurs would be better please?

It would be good to know how many people observe that effect, though even it is only one person affected that is one more than I want, so I will gladly change the colours.

You chose two colours with what I would call fluorescence. They clash. Find a colour wheel and choose more muted complementary colours. I could suggest thousands of pairings, but it's your choice.

Pedantry, William! It was YOU who raised it here in this thread.

I tried to find gentle colours to convey a peaceful message.

My choice is to choose colours that allow you to view the message without problems. So please help me in that choice.

I would have thought that those colours are muted.

Would complementary colours be more likely to produce strange visual effects?

Precision, not pedantry.

The colours you chose are not gentle - they are extremely harsh. They are not muted.

No, because they complement each other. The colours you chose DO produce a strange visual effect: where they meet, there is the dizzying strobe effect I mentioned. Can you not see it yourself? The edges of the letters appear to move.

So please help me in that choice.

Here's one of MANY online resources:

https://brightside.me/article/the-ultimate-color-combinations-cheat-sheet-92405/

The outer two rings are where you will find the more muted, 'peaceful' tones. The middle ring is where the brighest, harshest colours are - avoid those.

Mmm ... I'm not going to pursue this. I know from bitter experience it would be pointless (and I'd end up frazzled).

No.

I just don't follow how to choose two colours from those diagrams that will hopefully resolve the problem

I am trying to help. If you say which two colours you would like then I can try to produce that version and ask if it looks good for you.

I am stuck.

No, William. I'm not going to hold your hand on this, sorry.

You have the time to work through this yourself: look at it as part of your research. I suggest you try each pair together on your card, alternating background and text. Compare them and choose the one that is most pleasing. That does not mean the one that is most in your face. Maybe come up with four options, post them here all together and ask members which they find the most pleasant to look at.

Let us know how you get on.

A good tip for those of us who have Affinity Photo (which not all of us do, of course).

How about this version?

Here they are for comparison. The original one first.

Comments are invited on the altered colour scheme please, from @Ali and everybody else too please

[Ali]

The second one is much better. I can look at it, for starters. If I were to be hyper-critical, I'd probably take the pink towards a mauve shade (somewhere between the two), but as it is, it is fine now.

Presenting text (or any icons or glyphs or whatever) in colour on a background and making it work is part of the communication. You can't communicate effectively if some people cannot even comfortably look at the communication, so it is ENTIRELY relevant to your research, but hey, I gave you another opportunity to promote your localisable wotsits.

Hmmm William, are you secretly working with SciShow? Or is it mere coincidence that a mere day after you started this thread, they quickly covered the topic:

Why don’t you link to the post in question via the ‘Share’ option offered on the menu that appears when you click on the ellipsis in the top right-hand corner? Then the user will be spared the tedium of scrolling to find it, and there will be no confusion about the timestamp (which may differ according to the user’s time zone).

It just did not occur to me to do it.

I'll try to do it now.

Not being a designer myself, or having a natural sense of color, I find color wheels (which is what you saw at the 'Color Combinations' link) useful. They help you pick color combinations that work together; if the info at that site isn't sufficient, Google 'color wheels'.
