I have a 23" Acer S230HL and a 19" KDS VS-19SN using for extended display. I use a program called Filter Forge to make textures. My problem is they look different on each display, and I don't know what the color truly is. I made a grass texture with dirt in the background of it. On the LED the grass looks more green but on the CRT it looks more brown. My problem is deciding on which monitor displays colors more accurate.

Without knowing which monitor displays the colors correctly I am unsure of how my textures really are suppose to look. If I could get someones input as to if this texture looks more of a bright green or a darker faded green with more brown. That is actually how bad the colors vary between these 2 monitors. So basically the grass looks almost brown on the KDS, and bright green on the Acer.

I'm willing to bet you have never color calibrated your panels?

Only way to find out which one is "right" is with a colorimeter
 
Toshiba laptop's NON-LED screen: definitely more of your "brownish" choice. It is green, but far from a "bright" green.

Samsung UN46D6050 LED HDTV: In between I'd say. It's not a "bright green" IMO, but it has more contrast and isn't washed out looking. However, where the Toshiba's actually looks to show splotches of brown which looks kinda like dirt, it definitely is not resembling that on THIS screen. Also, the shaded areas, or what are probably intended to be much darker brown (not really appearing as such on either screen), are very very dark on this Samsung.


To summarize:
The Toshiba (ccfl) - a bit washed out so it kinda looks like brownish, yet still green. The thin lines are definitely light green and the background is definitely a dark green. The lighter shade splotches are clearly brown, but the darker shade looks more like a cross between a dirty "Forest Green".
The Samsung (LED) - crisp, but more contrast. Still not what I'd call a "bright" green, but not quite brownish by any means. The thin lines are definitely light green and the background is a dark green but "very dark" green in some areas. The lighter shade splotches are a dark brown, but the darker shade looks like a very dark green - borderline black except it definitely has color.


If you have a DSLR, you could always take a photo of something that has the greens you want and have someone (assuming you don't have it) open said photo in Photoshop. With my Canon it asks if I want to use the embedded color profile, to which I say Yes (pretty sure it's just Adobe 1998 anyways), and they always seem to look pretty much like they had in real life (on my Samsung). But I digress, from there they can color-dropper that area and then give you the hex code for you to then use in Filter Forge.

Correct, I have never calibrated my panels. Chances are I won't even know how to use a colorimeter, that is why I wanted to know how it looks on different monitors. To get an understanding of which one is more color accurate.

This is absolutely a perfect answer! I was so stupid and forgot that I could use hex code for the colors. I do have a DSLR and photoshop, so I think that would be the perfect way to go for me. I may have exaggerated that it was bright green because my eyes are a bit sensitive to my Acers contrast, but this also helps me to know which display I should adjust.

Thank you for the delicate and useful information!
 
This will do me till I get a little more knowledge about calibration. So both of your answers are much appreciated. Thanks!
 
The display gamma seems to have a MAJOR effect on this image.

This image looks brown at low gammas.
This image looks green at high gammas.
On all my monitors.

It's definitely not only a LCD/CRT thing, except LCD's commonplace default high gamma. CRT's usually have a darker gamma by default, which causes the brown.
I immediately recognized this was a gamma thing, due to Physics 101 -- Additive Color, because green+red = brown if balanced at a certain ratio. This image has a major green component, and a minor red component that balances very differently depending on gamma. Lo, and behold -- viola -- adjusted gamma, and got the brown. Adjusted the gamma again, and got the green.
 
FW-900 here.
The color looks about how you would imagine it should be. Mid tone greens with some yellowish highlights, the darker spots have shades of brown. It's not bright green nor dark brown, looks about right to me.

I used to make textures and map for games, and it always annoyed me as i always have pretty much used crt's and seeing my maps and stuff on other peoples monitors or lcd's really bummed me out.

I would spend endless hours on lighting and texturing, and then to realize it only looked as good on my own monitor. Seeing it on other peoples, the color was blown out - the shadows were not there, gamma was off ect ect.

Realize, most, or the majority of people don't calibrate their monitors nor are they extremely picky about image or color. My friend uses a tn display and to me it looks like utter dog chit. To him it looks just fine.

Really if you are using lcd to texture and map ect, you need to cross reference your work a lot. Look at it with default out of the box settings too, cause a lot of people plug in their monitors and that's how they leave them.

It's very similar in music production.
 
21" sony CRT here i concur with KG-PRime90 looks like he is describing when i put it in sRGB 6500K mode... but more brown with lowered brightness contrast and 5000k as i usually use this monitor..

the calibration software does most of the work.

i viewed the texture on several calibrated lcd's (all ccfl and led ips except for one led tn), and they all looked as kg-prime90 described it.
 
It's likely that both don't look correct.
The first thing you should try is to see if there are options for setting the monitor color temperature.
If there are some in the on screen display set both to 6500K. (the standard for working with graphics)
If there are gamma options set them to 2.2 .
It's likely that the monitors will look relatively similar once you give the monitors the same settings as the LCD doesn't seem to be wide gamut, but standard sRGB. So the more green/brown color is likely due to a different color temperature.
