The authors of the article propose their original bi-coloured solution of form graphics surfaces for a pair of component-type tetrahedrons. This solution is successfully implemented in generation of images as well as in development of unique framework models and aesthetic emblems. The emblems are a visual representation of a mirror-like symmetric unity of structure and colour contrast for a pair of component-type tetrahedrons. The research results have fundamental scientific, theoretical and practical importance for architectural design purposes; it will also foster generation of structural shapes. The original form graphics solution will enjoy intensive application in structural design, structural geometry and computer-aided modeling of images of geometric objects
