It’s a standard Color picker tool but it has some features I find it very useful when working with QlikView. It is probably safe to assume that we all have a color picker tool installed in our machines, but in case you do not. Ĭommon tasks are time consuming and when it comes to color it’s very common to find yourself trying to reuse corporative colors. It takes the guesswork out of designing for color blindness by showing you, in real time, what people with common color vision impairments will see. To avoid that potential risk that could ruin your app, you could use one of the pre-designed color blind safe palettes and/or you could test your app using a tool that lets you emulate a color blind environment.Ĭolor Oracle is a free color blindness simulator for Window, Mac and Linux. To create great looking QlikView apps you should be conscious that some people out there do not see colors as you do. Feel free to use, improve and distribute it.Īs discussed earlier in this blog, around 7-8% of world’s population has some short of different color perception. I created a QV app (see below) with these colors palettes to facilitate their adoption by our community. It was originally designed for cartographers but it’s a standard in academia for any type of data visualization. Created by Cynthia Brewer, Mark Harrower and The Pennsylvania State University. Some of the most popular color combinations are in. There are lots of content and good examples on the internet about color palettes sites like can provide you with some nice color combinations for your next project. It’s key to find a color palette that works and that lets business users consume information quickly and in an efficient way. If you are looking for more insight about color and interpretations I strongly recommend you to read Apeksha’s Technical Brief.Ĭolors are present in our apps not only in the charts but also in the backgrounds, tab row, captions, and so forth. A few days before, Apeksha shared some good tips about color usage in QlikView apps. Chuck showed us how to manage colors and alpha transparencies to increase visual perception in our dashboards making it clear for business users to consume charts. Finally, save the images as a JPEG using the same method you used to save it as a GIF in the previous step.We have been talking a lot about color recently. Then, go to the "olor" tab in the colorpix window, and use the buttons for the desired color values. ![]() If you'd like to see how your chosen images look in their original state, you can also open them up in Paint Shop Pro and set the colorpix window to the "Original" size. Fortunately, there's a really easy way to fix this - just download a freeware Photoshop alternative called Paint Shop Pro, which has a built-in "hex color" conversion utility. However, if you're using a Mac computer, the file might not be displayed properly on the Mac operating system, and it might not be viewable on many browsers. ![]() Because RGB color codes are more widely accepted, ColorPix can be accessed by virtually any computer. This is because ColorPix uses the RGB color code system, rather than the common CMYK color code system used by Windows. The only minor problem I have noticed with ColorPix, is that if you try to save an image as a JPEG, it will give you an error message saying that the file could not be opened. ![]() To save the edited image, simply click the "Save" button. Then, type the size of the image you want to edit into the "chart" section, and the software will crop the photo so that the exact dimensions of the new image appear. To zoom and manipulate the image, for example, you'd either need to move your mouse cursor inside the photo (which is very difficult to do, since the picture is very small) or alt-click the mouse to bring up the zoom tool. You can simply use the built-in Magnifier to enlarge a picture, click and drag on an image, or store a color value into the clipboard. Editor: ColorPix, like most other free image editors, is a handy little color picker which captures the pixel behind your mouse and converts it to a variety of other image formats.
