I have a PNG file on my Windows machine of a proposed logo that someone sketched out in PowerPoint. I am tasked with making a master version in Illustrator, and then saving various copies for web use, Word, etc.
The logo is a uniform red color, with white lettering. Simple enough.
Here's my question: When I open the PNG on my Windows machine (where I have PowerPoint) and also on my Mac (where I have Illustrator), the red shade looks darker on Windows. At first I thought it might be that my crappy Dell monitors weren't calibrated as well as my new MacBook Pro, but when I check the color with the eyedropper tool I get RGB values of (181, 10, 0) on Windows, and (188, 0, 10) on the Mac. Same PNG file, totally different colors.
What could be causing this difference? I'm not well-versed in color management profiles, is that what's tripping this up? And how do I ensure that the final logo looks the same across different devices?
EDIT: Here is a cropped portion of the PNG in question:
- On Windows with Paint.NET, the uniform color shows up as (181, 10, 0)
- On Mac OS X with Pixelmator, the uniform color shows up as (188, 0, 10)
- On Mac OS X with Illustrator CS3, the uniform color shows up as (188, 0, 10)
- On Mac OS X with Photoshop CS3, the uniform color shows up as (181, 10, 0)
What does it show up as on your computer?
EDIT 2 I created the PNG by taking a screenshot of the logo, with the indention of tracing it in Illustrator, so this is not a problem with PowerPoint exporting badly. The problem is with the colors in the resulting PNG file.
