Color numbers (for example #333300) are different in DreamWeaver and Photoshop.

I'm trying to use this color as a cell background and use the same color for a picture background but can't get them to match.

The Photoshop version of that color is ugly.

Anyone know a trick to find the exact match in Photoshop for a color number from DreamWeaver?

Thanks!!

That's interesting. I would think that the same RGB hex codes would show up the same (on the same monitor, using the same gamma settings). Are they radically different, or just slightly off? Are you sure that you're using the same color model for both, and not RGB for one and HSB or CMYK for the other? You're talking about both on the display screen, not one on the screen and the other ink-on-paper? You've checked that "33" is 33-out-of-255 for both, and not 33% for one?

All other things being equal, it sounds like one or the other program might be using its own gamma settings, which would affect the appearance of the output ("slightly different", not "radically different"). I use GIMP, not Photoshop, but I think PS does have its own gamma settings. If that doesn't solve the problem, go out and Google for photoshop dreamweaver pantone and see if anyone provides Pantone color matching between the two programs. If it involves Pantone, you'll probably have to pay real money for it.

A couple of defintions, in case you're not familiar with them:

gamma: the transfer function for how a given numeric value (e.g., 0x33) for a primary color (red, green, or blue) shows up on the screen (intensity mapping from number through a given display adapter and display screen)
Pantone: a company whose bread-and-butter is standardized color samples and matching between computer display systems and inks and dyes

I haven't had that issue.  Like MrPhil suggested, check to make sure you're in RGB in PS. 

Oh, I did have something happen that might have been similar.  Is the color dissimilarity before or after making the image?  i.e. did you notice it while in PS or after you had saved the file and placed it in the page?

If the latter, is it a jpeg image?  The jpg format is not a lossless format so the way it saves the data does affect the final image (the average of a block of pixles the size of which are based on your quality setting ... or something like that.  Very late, very tired, just got done with a looong drive).

So, if you have a mid to low quality jpg setting, it's going to mess with your colors more.  I had that happen when I did an oval image with a black border and my background color outside of it.  I had to play with the jpg quality until it matched correctly.  Too low and the background color was darkened due to "bleed" from the black border of the oval.  Thus show the image size by a rectangular block of slightly darker background color.

Sou & Phil, thanks so much for trying to help.  I'm embarrassed to say that I now cannot replicate the problem I had yesterday.  All is fine now.  I must have been in the wrong mode or something...or maybe my brain was just fried from working too long on the project.

Thanks again!!
