vru Posted July 16, 2004 Share Posted July 16, 2004 Hi I have a Compaq presario 2570US laptop with the following Graphics and Display: Graphics Card: ATI Mobility Radeon 4X AGP Graphics RAM: 64 MB Display Diagonal Size: 15.0 inches LCD Native Resolution: 1024-by-768 The problem is with blue color. The color i see blue on my laptop screen shows purple on other crt monitors. It also prints purple. Other colors also look a bit different but the problem is more with blue. I am attaching a sample pic. The sky looks sky blue on my screen but purple on other monitors. Please help. Thanks Vrushali Link to comment Share on other sites More sharing options...

Ernest Burden III Posted July 16, 2004 Share Posted July 16, 2004 What is the solution for this? How do i change the colors of my laptop. My renderings look purple to others. Change the color. It looks purple partly because it is next to a green. Link to comment Share on other sites More sharing options...
David Knourek Posted July 16, 2004 Share Posted July 16, 2004 Ernest, its actually a Starwars Lego figure of an AT-AT that I have modeled and working on a short with it also when I can get free time. *modeled in max and rendered with V-Ray* -dave Link to comment Share on other sites More sharing options...
Jeff Mottle Posted July 16, 2004 Share Posted July 16, 2004 The other alternative is to edit the video card color settings (in your video card driver) until it matches what you see on yor other monitor where it does show as blue, or buy an LCD monitor calibrator like the ColorVision Spyder. It's hard to tell whether it really is purple, your LCD screen is not calibrated, or if your other monitor is correct. Go into Photoshop and post the RGB or HSV values for that purple. If you go by the numbers, it does not matter what your screen says we can see how it really looks. One other important factor is the color space you are working in. It does not matter, but for us to test the color we need to be in the same color space as the color lookup tables change from colorspace to colorspace. Ie the actual RGB values change as well. In photoshop your colorspace settings are in Edit->Color settings We need to know if color management is turned off or what the working space is (Adobe RGB etc.) Link to comment Share on other sites More sharing options...

If you go by the numbers, it does not matter what your screen says we can see how it really looks. I already did that for him, posted the result. I opened the file without applying any profile. The color is blue-ish. But it looks purple to everybody. So change the color. Link to comment Share on other sites More sharing options...
Brian Cassil Posted July 17, 2004 Share Posted July 17, 2004 Ernest, its actually a Starwars Lego figure of an AT-AT It looks more like an AT-ST. The AT-AT's are the ones on four legs. (Wow, am I a geek or what?) Looks awesome though. Link to comment Share on other sites More sharing options...
Fran Posted July 17, 2004 Share Posted July 17, 2004 Hi Vrushali, I had a problem with my output having a greenish cast. I went to Walmart and printed a high-res jpeg out at their Kodak kiosk. Then I brought the image up on my monitor (a CRT) and adjusted the actual monitor controls for RGB until it matched the printed output. If your laptop doesn't have "hardware" controls for the monitor, you'll have to do as Jeff suggested and go into the Advanced Display Properties settings and adjust things through the video driver. I find that LCD displays tend to be on the "cold" side of the color range - ie more toward the blue. Link to comment Share on other sites More sharing options...
vru Posted July 19, 2004 Author Share Posted July 19, 2004 Hi All I really appreciate you helping me. I have little knowledge of clor management and video card driver. So I am reading the posts again and again to figure it out. I am attaching the color values and the color settings. I dont know anything about color settings. The color values are the same as posted by Ernest. I have created the image from ArchiCAD. So I am wondering how I can change the color if the sky is more than just a plain color. I am totally confused about this and also worried about changing the video card settings as I dont know how it works. Thanks Vrushali Link to comment Share on other sites More sharing options...
Ernest Burden III Posted July 19, 2004 Share Posted July 19, 2004 It looks more like an AT-ST. The AT-AT's are the ones on four legs. (Wow, am I a geek or what?) The AT-ATs were the huge camel-like transports from the second movie (Empire Strikes Back). I think they were mostly designed by Syd Mead. Link to comment Share on other sites More sharing options...
Jeff Mottle Posted July 19, 2004 Share Posted July 19, 2004 Vrushali, I did up some PDF documents last year explaining how to set up color calibration on your system, but please bear in mind that it's pretty much all or nothing. Doing only half the steps is worse than doing nothing at all. http://www.cgarchitect.com/vb/showthread.php?t=900&highlight=Spyder Also, I'm not sure if you have just changed your color settings, but until you understand the implications of what you are doing (read the PDF above) I'd set your Color management to off. As far as editing your video card settings, don't worry about going to the color correction tab (or whatever it's called with your driver) and messing about. You can always reset it back to the default. Usually there is a button that does this. Cheers, Jeff Link to comment Share on other sites More sharing options...

Christopher Nichols Posted July 20, 2004 Share Posted July 20, 2004 You know for just $99 you can get a really good color calibration system for your monitor. At work we use a very fancy one, but Pantone offers a good one. http://www.pantone.com/products/products.asp?idSubArea=0&idArea=2&showNav=31&idProduct=321 Link to comment Share on other sites More sharing options...

I did not understand how you solved the problem of green cast. Could you please elaborate. Thanks Vrushali Link to comment Share on other sites More sharing options...
Ernest Burden III Posted July 20, 2004 Share Posted July 20, 2004 My prints have a yellow cast to them. I am not sure whether it is only on my HP printer. I did not understand how you solved the problem of green cast. Could you please elaborate. She did an 'eyeball' reverse-profile. She had an image printed and adjusted her monitor colors (usually throught 'dislay properties>advanced') to match how the print looked. She skewed her display to match the output. So in the future her monitor will already be biased to the output. That is not the best way to deal with the problem, but it is the easiest. Better is using a monitor profiler to set a profile used in the driver. Better still is to profile your output device--either yourself or via mail-away services. You print a 'target' image and a device measures the bias and then you use that profile when printing through Photoshop. It's complicated. Link to comment Share on other sites More sharing options...
vru Posted July 20, 2004 Author Share Posted July 20, 2004 Thanks, I finally found the advanced display properties. Looking into profiles and color calibration documents posted by jeff. Link to comment Share on other sites More sharing options...
