This is called chromatic aberration. Here's an example from Wikimedia: The Oculus Developer Guide (PDF) provides a nice explanation: Chromatic aberration is a visual artifact seen when viewing images through lenses. The phenomenon causes colored fringes to be visible around objects, and is increasingly more apparent as our view shifts away from the ...

The browser doesn't really care which format the color is in, performance is negligible. As such, I'll focus on the decision's effects on the developer(s) and the use cases. A lot of developers find HEX values easier to read than RGB or HSL. As such, I tend to use HEX so that the next developer working on the project may have an easier job, even slightly ...

Web sites can contain JPEG, GIF,PNG, SVG format graphics. Which ones should be used, and when? For photos: JPEG if there is no need for transparency. PNG for photo graphics that need transparency. Whilst not 100% true, it's a good rule of thumb. Check out the other answers to this question to learn more about the other formats. Also, check out ...

For people who don't have Adobe Photoshop, here's a free and cross-platform alternative: Using ImageMagick, it can be done in command line convert lQchR.png -auto-level -white-threshold 78% fish.png This may require some fine tuning of the white threshold value, but it's quicker than GUI especially when you have multiple pictures: convert *.png ...

It really depends on what you want to do with the colours. If you're plotting multiple plits in a single graph, you need way different colours thanfor a good colour scheme you'd make a poster design with. Since Zach already provided good colours for the contrasting-graph scenario, I'll add my advice for creating a balanced colour scheme. Since the current ...

Colors similar to these might work, assuming the colors are for team colors or something similar. #8C8C8C #EB2E32 #A349A4 #141414

This effect can normally be found under the name RGB Twitch, RGB Slide, RGB distortion, RGB displacement, etc. So, from what you can see, this is a visual reference to the old RGB screens that on occasion would show the image with the colour channels displaced, thus resulting in unexpected or undesired effects. There are several ways of doing this, and ...

I suspect the job is actually a 5 color spot (maybe + black) and not CMYK + Silver. I'm not certain if the black is actually part of the spot color piece. It does look like there are 2 separate pieces of packaging in that photograph. So, the black ramp may be an entirely different package. The fact that it's a spot color job is indicated by the color ramps ...

As far as I am aware, colored brushes are not possible in Photoshop. As for your alternative question though, definitely! Just use gradient maps. For instance: If you have a grayscale gradient like this: And you apply the following gradient map to it (accessible from image/adjustments or as an adjustment layer): You'll get the following new ...

Select All and choose Edit > Edit Colors > Recolor Artwork. You can then alter colors easily regardless of them being gradients or solid colors. Then just click OK when you're done. This will not alter any linked or embedded raster images and may or may not alter raster effects.

I found the answer by checking all my layers. My layers are very organised, in groups etc. Within one of my CLOSED LAYER GROUPS, ABOVE THE SHAPE LAYER I was working on, was a hue and saturation layer. This was affecting the colour I was trying to specify. So simple, yet so frustrating. And there I was thinking my new Photoshop CS6 was somehow corrupt and ...

I make generative art works which employ color schemes downloaded from kuler.adobe.com as ASE files.I improved the script provided by plainclothes to make a useful multiple ASE file loader tool to load all the color schemes I downloaded in one go. The tool uses the ActionScript File.openDialog class to select multiple ASE files from the download folder. It ...

John should be correct if you are exporting as CMYK, look up "Color Gamut" online and you can see the difference between RGB and CMYK color models. You might want to check to see if the box you have the picture imported into in inDesign has a very light fill applied, as well. Often that will shade a picture when exported if not turned to "none". We get ...

In the wikipedia article on spot color: In offset printing, a spot color is any color generated by an ink (pure or mixed) that is printed using a single run. [CMYKOG...] The two additional spot colors are added to compensate for the ineffective reproduction of faint tints using CMYK colors only. However, offset technicians around the world use ...

Interesting question! I honestly don't understand Luma, Chroma and Chrominance well enough to explain why it is or isn't increased by adding to one or more of the channels. It might increase them, or it might not. I wouldn't know. It definetly does NOT increase saturation. If we start at (0, 0, 0) and add the same ammount to all channels, the saturation ...

Send your client a PDF format but save the file as sRGB. Their monitor will display the colours better when they open it. That's just for them to view. But if they having more issues. Then send them a Hard copy proof.
