In the previous article we introduced the colour theory. Now all this theory has to become practical and the first idea that has to come to your mind is to steal colours from an image (you can do it directly on PowerPoint). If you want to give slides a style that is consistent with a certain topic, you can choose an image related to that topic and then select a colour for the text that comes directly from that image. (To do that you can open PowerPoint or Keynote, select the option to change the text colour, click on the brush at the bottom of the window that pops up and place the cursor on the part of the image you want to pick the colour from).
For example, do you want to create a presentation to introduce your company? You can extract the exact colour of your company's logo and use it consistently throughout your slides (why look for a similar colour if you have the same one at home?). In this example the colour of the headline (Luxottica Group) is exactly the same as the colour of the logo.
At this point you can raise the bar and combine this technique with a super useful (and free) online tool: Adobe Color CC. This tool allows you to create colour schemes which are consistent with the theme of your presentation in an intuitive way. You just need to upload an image and the tool automatically extracts the main colours for you (by clicking on Colour Wheel at the top, you know exactly what colour the tool has selected). Not only that, starting from an image and a colour extracted from that image, you can automatically create professional colour schemes (monochromatic, analogous, complementary, etc.)—all this without being an expert in colour theory. This is the best way to make a presentation look uniform and professional.
For example, for this bar chart I didn’t choose any green, but exactly the same green that was generated by the tool, starting from the original image I had uploaded. I only adjusted the value in order to create better contrast, but the hue (the “colour”) is the same.
