Three problems when code in julia

[XaydBayeck]

1. The keywords "end" also be use in matrix.
   At this point, it can represent the last element/row/column.
   But this extension can not recognize this situation.
   
2. When the nesting level is greater than or equal to 3 levels, the outermost two levels are the same color
   
3. Anywhere, it's wrong.
   

PS:This is my settings

    "workbench.colorCustomizations": {
        "rainbowend.deep1": "#e79191",
        "rainbowend.deep2": "#92efff",
        "rainbowend.deep3": "#a4a2ff",
    }
