I have Photoshop CS on both my comps, on my dad's all the colour look fine but on my computer the colours look normal except when you are using any blue it looks a funny purpley blue colour but when you save it it looks normal. Does anyone know why this is happening?

can anyone help me?

sounds like a bad vid card or monitor....nice double post

Gotta go with maskedviperus on this one - if it does fine on one computer and not one another its probably the computer and not the image file.

Ah, but where to start?

Maybe your monitor just has a blue adjustment out of phase? Maybe a gamma correction curve in the software is set different between the two machines? Maybe you got a bad wire in the cable between your monitor and your vid card?

Try to borrow Dad's monitor and swap it to your machine temporarily just to help debug your issue.

If the image "fixes", it's not the vidcard or the software = it is the monitor or cable.
If the image is still "broke" ,it's not your monitor or cable = it is vidcard or software.

And of course, check with your vidcad manufacturer for driver updates......

I'm betting if everything looks normal EXCEPT in Photoshop CS [Play with Paintbrush and see], then that's your culprit. Only I'm not a Photoshop guru so I can't tell you where to hunt.

Try some stuff let us know what you did and what happened.

just tried the paint idea with my monitor and everything looks normal so it must be something in Photoshop any ideas?

Try going into Edit > Color Policies through the menu and looking at your "Working Spaces" options.
Are they the same in both versions of P'Shop?
If so, click the Advanced Mode checkbox and compare the now visible settings on both rigs.
One or more of the settings could be different between the 2 computers or perhaps one or more monitors were not calibrated when P'Shop was installed.
Check those settings and get back to us.

Go to control panels > sytem > hardware tab and click on "device manager" and right click the monitor and choose properties to see what driver your monitor is using, it's probably Microsoft's Plug and Play by default. If you have or can find a specific driver for your monitor, load it. This will eliminate any guess work about what "Phospors" your monitor needs to be set for when you calibrate.

Then go to control panels and run Adobe Gamma. This was loaded when you installed Photoshop. Click on the "wizard" button and follow the instructions. Once you're done reset brightness and contrast to a comfortable level. When you open Photoshop it will know exactly what kind of monitor you have and how to adjust for it.

I think he is using a bad color profile in PS like godfoot was saying.

If it was a bad monitor driver then paint would look bad too...

Try to put your dad's monitor on yoru pc. If the same thign happens then it is almost definitely a screwy color profile.

I disagree, most people will never change color settings in photoshop and the defaults will work just fine for them. Most of the other settings will remain looking exactly the same unless you do something funky like assigning a printer profile to a RGB color space then convert to CMYK. These settings are the color spaces Photoshop uses to work in, not how the color is viewed on the monitor. It doesn't matter if you work in sRGB, Adobe RBG, ColorMatch RGB, Lab Color or any other color space you can load via ICC profiles. They will all look the very similiar on screen. The only time color will shift in this scenario is if a embedded profile in a file does not match the working profile and only then if it is not converted to the working space.

CMYK profiles will approximate how a image will print, these can look very different depending on the seperation set-up. But few people outside of professionals like godfoot and myself need ever worry about CMYK set-ups.

Monitor color is controlled outside photoshop via a monitor profile. The relationship between this profile and the color spaces you're working in determines what you see on screen in photoshop. Paintshop displays the same as the desktop with no color calibration. For printers and designers, these profiles can help approximate what a press is able to print on screen.

You create this profile for use with Photoshop via Adobe Gamma or a host of other color profiling software. Profiling software can range from a freebie that comes with your video card to programs such as Sony's Artisan which uses a sensor you attach to the screen via suction cups to calibrate. And to work with CMYK, there are programs like Greytag's ProfileMaker bundled with spectrophotometers costing thousands of dollars.

A monitor driver that matches you monitor is useful as it will provide exact data on phosphor, sync and other info, including the default ICC profile for it, but it is not absolutely necessary to create a monitor profile. Lot's of people create profiles without even knowing it. It's also very easy to overwrite a profile or replace it when installing new vid cards or programs.

To see exactly what profile you're using for color go to display > properties > advanced > color management. In the pane will be all the profiles associated with your monitor. If you've installed a monitor driver you'll have one probably named the same as the model number. If you've ever calibrated your monitor using Adobe Gamma, you'll have one with the name you choose when you did so. You'll also have one if you used software that came with a vid card. This default profile will be in the upper position.

One thing you should NOT do, is one more than one calibration program. They can conflict with each other in very strange ways.


This all may be totally unrelated to the problem at hand...but good info anyway.

Don't forget about Potatoe Joe too.

Definately good info, I picked up something out of all of that even. Nice explanation as well.
The other thing I had in mind when typing my original response was after clicking on the advanced mode checkbox. Under the Advanced Controls section that becomes available, there are 2 checkboxes (at least in PS 7, not certain about CS), one for desaturating monitor colors and a second for blending RGB colors using a particular gamma. These are the main things that I thought might potentially be culprits in this instance, but AntiM is right in that if only a default SVGA driver is being used it may change the way things "should" look. A proper driver for your monitor is always best to have.

i installed the drivers that came with my monitor and i will try all the things you guys have suggest and let you know how i go thanks everyone for all your help

i fixed my problem what i had to do was change the colour profiles in the edit>colour settings and in the advanced tab when i created a new document to Monitor RGB and then once i did it the 1st time it has stayed yay

thanks everyone for your help and suggestions though
