Project was based on Ionic3 with angular and SCSS.

Ionic has an SCSS array with colours that generates countless CSS classes for each combination of color-component.

Smh I managed to reduce the amount of colours in that array and reduced the overall size of the final CSS by 48% (from ~8MB to 4.1MB)

Of course the overall app had no performance increase BC the problem is the main.js file which is about 12MB with no lazy load
