I'm newbie graphic designer (for iOS app, Android app and prints). I have watched color management course. They suggest me to use the calibration machine like X-Rite ColorMunki Display or Spyder5 Pro. (http://www.pcmag.com/article2/0,2817,2414919,00.asp)

I already understand that part. But I have few more question about color management. In some video it says that I need 5K color temperature light bulb and have to wear black or grey shirt to see the accurate color. My room is quite yellowish. Should I buy some Grey or Black paper and cover the wall? What color should I buy Grey or Black? or I do not have to go that far?

I make design on my computer and send file to print company. and Use those design on my iOS app and Android App.

I have attached the photo of my room, you can see the yellowish and it become even more yellowish when the sun fully shine. It is because the color of the wall is quite yellow.

The thing with the black and gray walls is more related to verifying printed proofs or for example, calibrating a picture with its version on screen. Yes your yellow walls will affect how you see colors and corrupt your interpretation of them. But you need to keep in mind that if you're not using any proofing system and you plan to approve the proofs at the printer instead, you can always approve the proofs in the printer's "calibrated rooms" to be sure.

Even for them, it's very hard to get to set up the perfect environment for this as many companies have to use industrial fluorescent lightning that make color more bluish; the real 5k light bulbs are way too expensive to be used everywhere. So one way they make sure to have the perfect lightning to verify colors is by creating a box for this where they can add the perfect 5k light bulb too. It's usually a small black box with the 5k light, and they look at the printed proof in it. The bigger place will have an entire small room set up like this. If they do color management of high level, they will set up these computers in that environment but rarely the whole design team.

Ideally, you should have walls and curtains with neutral tones; they can be light gray or white. If you notice that your walls reflect a lot of yellow, that means you might want to modify the paint on your walls.

About the red shirts, maybe they mean you shouldn't wear bright colored clothes when you calibrate or do projects that require very precise color adjustment (eg. light colors.) Otherwise that's a bit overkill for freelance work. It's true though that you should avoid buying anything too colorful for your office for now on (eg. bright colored furniture or accessories.) The tips you've heard were good but targeting hardcore color management and calibration, and before you start changing shirts to work, you might want to simply get the right tools to calibrate your display properly, paint those walls and fix the light in your room. If you can't buy the X-Rite then at least fix your walls and lightning to be more neutral. The goal is to work in a neutral environment.

Regarding the light, you can buy these 5k light bulbs but just so you know, they not very far from the standard light bulbs; just don't buy the "energy saving" type, they're like fluorescent. The "ideal" light for color is the noon light at 12 and that's the condition you need to try to reproduce in your own office. That's what the 5k light bulb actually help for. For your web projects, it's not as important as long you're in similar conditions as the people who will look at your apps and websites.

When you might want to be careful is when you'll work on very light skin or sand tones, or any light color that have very low percentages of CMYK. You'll end up learning how to trust the CMYK numbers instead of trusting only what you see on the screen. You'll also end up learning that nothing is ever perfect and the goal is always to get as close as possible to perfection; you won't be able to control the 1-2% "too-much-cyan" on the press but you'll know how to choose your colors properly to compensate for all the little imperfections of printing! Or simply choose to print with a Pantone.

If your work requires you to do a lot of skin tones or broken white projects, for example wedding catalogs and magazines, then yes you should really try to get to the optimal conditions.

Now this is a personal suggestion; you don't need to go crazy with all this but yes you should try to get closer to an ideal. And for your proofs, approve them outside under the sun if you're not certain or ask your printer to go in one of their room that is adjusted for verifying proofs.

  • Just want to get a little knowledge about the color for the wall. You said white or light grey, why not mid grey or black? Sorry I'm newbie ^^" and about the calibration machine. I will work both day and night. I wonder what the function light measure do? Do they just compensate the brightness of the screen with the environment light? if it is only that. I think make it stay still is ok for my project? Aug 17, 2015 at 12:30
  • Mid gray or black are fine. I suggested light gray or white because lot of people can't or don't want to use dark paint! Calibrate your stuff during the day, but work whenever you want, preferably with another light source than only the screen. It won't affect the way you perceive the color on your screen that much and you can verify your print projects during the day. You could work in total darkness but your eyes are also "calibrating" so yes it's all about compensating; There's something about the eye cones & rods here: hyperphysics.phy-astr.gsu.edu/hbase/vision/rodcone.html
