If there is something that is characteristic to the icon packs thatSergei Kokota has available for download at Flaticon on his profile, is their muted colors. At a glance, you can see that these soft colored icons are very easy to the eye and, even if they are subtle, manage to catch your attention with their clear design.
Of course, Flaticon’s icons colors are editable, but you will definitely love the perfectly balanced palette that is common to all of these icons. Available in 24 packs, Sergei has almost 900 different icons available for download.
The themes for these packs include a lot of variety: you can find sports icons, like running or hiking, space, food and drink (including ice cream!), finances, SEO and technology. All of them have an uniform style and will match perfectly if you use icons from different packs.
The line art in these icons isn’t black by default, but instead a grey color that really suits the general palette. In any case, if you need to, you can edit these vectors with Illustrator or another vector edition software and remove or edit the colors, recolor the lineart, or resize them.
