Default Here's how you make a colour changing background on a mac

I found a really easy way of making a background that changes colour subtley so it's not off putting on a mac.

I made an abstract image in illustrator, lots of blending styles over the top of each other are good for this and fairly similar colours nothing too opposing.

Then I made an action in photoshop that changed the hue by 20(or whatever value you choose) then brought the image into photoshop and applied the action saved it as a new file, keeping the original.

I then repeated the action with the new file and saved it as another new file.

Basically your changing the hue and save a new file and repeat it untill it gets back to where it started.

Number the files 1.1, 1.2 and 1.9 then 2.0 etc (so they go in the right sequence of colour) and put them in their own folder.

Go into desktop and screensaver in system prefs and select choose folder in the desktop section and choose the folder with your images and tick the change picture box and set it to 5 seconds (or whatever you like).

Because it blends between the images and the hue changes gradually you get a colour changing effect.

Enjoy!

Just out of curiosity, how long did it take you to work all that out? Sounds like one of those very long tasks!

Well I was just messing around choosing a different background and I picked one of the default ones but set it to change picture. I noticed how it faded in and out and thought if I had the same image but just changed the colours it would appear to be an animated change.
I did animation and visual effects at university so I've done similar things before but It didn't take that long I thought I would just explain it well, because there's so many tutorials out there that are a bit vague.
And I did it on a friday afternoon when I was bored

Well, at least you weren’t really wasting your time!
