QAPF, Gabbroic And Ultramafic Rock Classification Schemes

The idea with these pictures was to color them by using the colors (most common) of each corner mineral and blend these colors as the percentage of mineral changes. QAPF diagram represents only the normalized felsic (light colored minerals) part of the rock, so for this illustration I avoided adding mafic (dark colored) minerals. But after posting it on few social platforms, I realized that people naturally miss mafic minerals when they see granite, diorite or any other, especially gabbro. Similar situation with other schemes I posted here. I have some ideas how to improve them. So, if you plan to copy these schemes and use them, either wait until I post improved versions or make sure you really understand why they are colored this way 😊
