Coolors is a colour palette generator. It can either generate an entire palette randomly or based on input such as a logo or manually entered colours. There are many settings available to adjust colours by shade, hue, saturation etc. as well as for colour blindness.

How have you used or intend on using this resource?

I have used this resource in website interface design. I will either upload a logo and generate a palette based on the logo, or pick a primary colour from the logo and generate the palette based on that primary colour. I will then hit the spacebar on my keyboard to continue to generate colours until I find an attractive set. The "padlock" icon is useful for locking a colour I like so it won't change while the others are generated.

Why would you recommend it to other people?

Although I used this for website design it can be useful for report design too. I would start with a single primary colour that looks good for your main headings, then add that into the colour palette and lock it so it doesn't change. Hit the spacebar key to generate colours until you see a set that you like. I would then use those generated colours for various elements of the report, such as quotes, tables, boxes, data visualisations, etc. For first timers I recommend clicking the question mark icon to view the tutorial.
