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.

I wanted to let you know that, last month, we launched a FREE Color Palette Generator that you can find here

VOCSO's free color palette generator is the easiest way to find suitable colors for your designs. You can use it whenever you need to design a new website, logo, create digital art with schemes or anything else related—in just one click! It provides relevant and beautiful combinations that are perfect for any purpose of yours at all times.

VOCSO color palette generator can help you explore and select a range of colors for your design. It is important to use the right type of tone in voice while designing websites, apps or other digital products that are used on mobile devices because different tones come with their own set of advantages and disadvantages. With this tool you can easily generate a new custom colored palette, which is great for graphic designers and business owners who are managing website and mobile app design by themselves or with a team. You can choose multiple color palettes with the hex codes! If you are having trouble deciding on colors then this program might be good for your needs.
