refactored flow cells, added colors for lab (#78)

* made better flow cells

* made cubical desaturation

* made colorfull lab nodes

* colorful lab nodes for all text ones

* all lab nodes are colorful

* disabled lazy loading on heroes

* fixed color calculation hook

* fixed lab color gradients calculation

* fixed cell text on flow
