I am "working" on an application which is remotely like a vector drawing app.
It has handles on some curve that can be used to manipulate the curve.
I want to hide the handle by default but make them reappear when close enough (opacity animation).
I want to give handles a hovered style (i.e. when mouse down will click it)
I want to give handles a selected style (when you drag a select handle, all the other selected handles move with it)
My handle look like a white circle with a black outline (at the moment).
I have a "selected pen" which as black and white dash moving over time.
Now I am not sure how to do the hover style (and that is my question).
Initially I was planning to have a pulsating and translucent red outline but.. it's no good for color blind people...
What could I use for hover style do you think?
The best answer is UI guideline and idea on how to cope with color blind people.
Plus I heard there are many kind of colorblindness (to make things more interesting hey?)

Pulsating makes me think of the <blink> tag and websites using comic sans.

I'm a "mild deutan", meaning I have some problems with red-tint when it is dark. Doesn't mean that I can't see your pulsating outline, it just won't look like the intended color-scheme. If your outline is a brown background, I will have more trouble, but so would you.
Pulsating red on white is very visible, even to colorblind people. Key there is contrast. Set your windows-settings for the colour scheme used in windows to "high contrast", and you'll see what I mean 
Look for RGBlind (FF extension) to view your page as a specific color-blind person, and it will change the colors for you to similate it. Similar online service here[^].

It's for WPF app!
I just used HTML language (style) as it is easier to understand....
Anyway thanks for the link!
If you can see red on black and white then it should be fine. Good to know!

I would gave the same advice and link for WinForms; you can write a HTML-page and test your color-codes.

It's not invisible, I just get the colors wrong

This has been posted before, but perhaps it will be of help:

lol!

If it comes to it, just make 'em bold on hover.
It makes the text dance a little, but makes the point.

Simple. Have Clippy pop up saying, "I see that you are hovering your mouse near a curve, would you like to select it?"

I think we shouldn't put a lot of effort into propping up aberrant physical deficiencies. Let the color blind live in the desert, away from normal people.

Hey, now.
(Not that you're wrong.)

What about the partially color blind? Can I live halfway (of normal people)?

increase the border width on hover?
If you are drawing the handle borders, this could entail just drawing an extra border around the current one.

I like that.
The user is manipulating he handle so I should change the handles., But hey they do have a border!

It looks good, but ... so did the trailer for "The Farce Awakens" ... 
Maybe I'll wait for the DVD.

Me, too...
No, I'll wait for the book...
No, I'll wait for the imdb blurb...
No, I'll wait till everyone's forgotten about it, and no-one talks about it, any more...
... Then I still won't waste my time watching it.

or the remake, of the remake, of the remake which was released straight to DVD.

In the case of Star Wars, remember, they're never "remakes", they're "meant the way to be seen"...

Every new movie sucks more than the last. Reminds me of remakes of remakes. The spins offs, so far, all shite.

I quite liked Rogue One. I thought it was the best of the whole bunch really. I don't have that much of an issue with The Last Jedi, other than Leia doing "Zombies on Ice in Space" mostly, or with the Force Awakens for that matter.
The originals, to me, are targeting way too young an audience. Rogue One is the only one that's reasonably 'adult', to me.
I have them all (other than Solo) but I find the original 6 fairly hard to watch, though I get the historical significance of IV. When I was 13 years old I road my bike to the theater probably 5 times to watch it. But now I find it hard to get through any of the original set.
I always think what it could have been had it targeted a slightly older audience.

Where?
It seems anyone can be a fully-trained force user now, without having to spend years with Yoda. Resurrection without training? I'm not going to see anything Star Wars again.
