How to change the transparent color of the Finder icon preview

By transparent color, I mean for image files like GIF or PNG that have transparent areas.


Right now, I see those transparent areas as black in the icon preview in the Finder.

Maybe I'm just imagining things,
but didn't it used to be white, by default?

I think I did something such that it's now black.


Would it have something to do with the fact that I've set all image file types (JPEG, GIF, PNG, etc.)
to open with the image viewer application Xee?

Open Preview > Preferrences and goto the General tab

Click on "Window background color" and change it to whatever the color you prefer.

That controls the color of the transparent areas (as well as the color of the background) in Preview,
but not in the icon preview (thumbnails) in the Finder.

It's still black in the Finder.

shouldn't have anything to do with default app, since finder should be the only thing that has an effect here.

can you post a pic of what finder looks like when this happens?

is the rest of the finder background white?

i thought the transparent color was referenced within the GIF, and it didn't matter what it appeared to be in preview. Because the GIF itself tells the system, my black=transparent, or my white=transparent

Of course in Adobe, transparent=transparent

not sure that that's how it works. you can have black and/or white in a gif, transparent is the lack of color. most programs (finder and explorer included) should register those areas as transparent and let you see the background that the app uses.

< note: my cat is a .gif, save it and see how it behaves.

But the thing is, back in like Win95 days I had a program and I had to chose the transparent color. And the options weren't just black and white.

weird. with photoshop, ps elements, and the gimp i've never had to choose that (or maybe it defaults and i never noticed?). it just alwasy shows up transparent...

i'd still love to see a screen cap of what he's seeing.

yah screanshots are very handy for troubleshooting, and aiding in fixing.

still having the issue remain?

Ack, sorry for the late reply.


Yes, the Finder window background color is white.


Here are some screenshots:

Let's take this GIF image as an example:





This is what that file looks like in Finder:



(Here, you can see that the transparent areas are black, as previously mentioned.)


And in Preview:

Bump.
