Eyesight problem.

Hi sorry a reply was long in the making 🙂

Go to system Preferences, select "Universal Access", click the "Seeing" tab and at the bottom of this window first click "Grayscale" and then play about with the enhance contrast till it's to your liking.

That may be possible by creating a custom style sheet and telling Safari and/or Firefox to use it in preference to the style in the HTML from the web pages.

I can find the place in Safari prefs to enter the CSS selection, but I'm afraid I'm a bit (actually a lot) out of practice with CSS, but I'll see what I can do if I can find the time.

Meanwhile, if there's a web designer out there who can knock one up before I get back, all the better.

Play around in a word processor and find the best colour for your sight. Use the RGB sliders to find a good balance.

A quick trial in TextEdit suggests a starting point of RGB 205.0.0 might be near.

Let us know what you find best and I or a better qualified person will try to give you something to copy and paste.

"is such a minor variation really worth the trouble."

Depends if it really helps. I have some problems with variable eyesight due to the corticosteroids I have to take, so I know small differences can sometimes have disproportionate results.

Might be a while before I can get down to this though, so please bear with me.

As for the name; I was listening to Dvořák when I chose my Apple ID…

Never mind as long as you find a solution that's all that matters - best of luck!

Well, I have to report a failure so far. I've got a style sheet that works with simple sites like my own website, but has no effect whatever on this site or BBC news or any other site I tried out in the 'real' world.

Have to give up for now, I'm afraid, but I'll gnaw at it a bit when I have the time.

Hi 🙂

should colour everything... (does here) you'll likely want to add something to show links at least

Spot on Andy! Told you I was rusty.

Yes, the links will need correcting back. I'll play with that later this evening. got to go do the chores and get my tea ready in a mo,

Thanks for that 🙂

Actually, I now have something that appears workable for the most part. The link colours don't seem to get to some frames, but overall it's a start and you can play with the colours to optimise them for yourself.

Create a new TextEdit document, and name it something like SafariStyles.css; the only important bit there is the .css extension.

Copy and paste this into the document;

* { color: #600000 !important; }

a:link, a:visited {

color: #355491 !important;

text-decoration: none;

}

a:hover, a:focus {

color: #4262a1 !important;

text-decoration: underline;

}

a:active { text-decoration: none; }

Save the new document and place somewhere convenient. As you will need to play with the colours a bit, I suggest you make a copy of the document (highlight the file and press ⌘D). Keep that copy unaltered and you always have a reference point to go back to if you feel you're getting muddled with the changes.

Next, open Safari preferences and go to the Advanced tab. There's a drop down for Style sheets. select 'other' and navigate to the new file. (You might want to change the minimum text size while you're there).

Quit Safari and relaunch for the changes to be effected.

You can then tweak the colours to suit. The # indicates that colours are shown as hexadecimal, 0 to 9 followed by a to f to make up sixteen digits. #000000 is full black, #ff0000 is full red. The number pairs are in the order red, blue, green, so starting with a red, if you alter the second pair you move towards purples etc.

I've started you off at #60000 for the red. increase the first pair for redder, decrease for browner.

Any time you make changes, save the text document and quit and relaunch Safari to see the new colour.

Works for any browser that will allow you to use a local stylesheet.

Any probs post back.

Any input from Andy or others also welcome.

Oops!!!

Major c***-up there;

The hex pairs are Red, Green, Blue, not as I stated, so starting with a red set, altering the third pair will tend towards purples.

Post was up for over an hour and no-one pulled me up on that? You're all slipping! 😉

Is a very good starting place for seventy one to try some colours...

some sites, like these communities, where much of the text on main pages is actually linked - might need the red, or another shade of it, used for those too.

Sounds reasonable. I plucked those link colours from the page source, so of course the OP can play with those as reqd.

I'll continue to experiment a bit myself as and when I have a spare moment.

Thanks again Andy.
