The logo is a graphic comprised of the wordmark (logotype) and figurative mark (symbol).
The lettering is created using the Danube typeface, and the artist made some improvements. The vibrant color palette chosen for symbol heart to evokes a sense of vivacity and vigour.
Use the complete logo. The only time you should use the symbol alone is on the Virtuos products or social media channels where there are other elements to help the user recognise the brand.
