I always like to see companies use trained professionals when it comes to branding and design.
However, there is a time and a place for a tiny bit of DIY in your design work. For example, there is a lot you can do yourself when it comes to email marketing, newsletters, LeadPages, and social media.
So for this kind of DIY, here is a great tool I've been introduced to recently - Adobe Colour.
It allows you to create colour palettes with complementary tones.
Use one of their existing palettes, create your own from scratch, or upload an image (logo or photo) to match. Genius!
