Extract "Red" "Blue" "Circle" "Black" from "RedBlueCircleBlack" using capital as delimiter?

Question

Is this a RegEx problem?

To note: there will always be only four items, each starts with a capital letter, each will be in order (color,color,shape,color): "BlackWhiteTriangleGreen" etc.

So,

    a="BlackWhiteTriangleGreen"

yields:

    c1 = "Black"  
    c2 = "White"  
    S = "Triangle"  
    c3 = "Green"

EDIT: referencing the post suggested by Alex K., an AS3 solution as follows works:

    private function UpperCaseArray(input:String):void {
        var result:String = input.replace(/([A-Z]+)/g, ",$1").replace(/^,/, "");
        var b:Array=result.split(",");
        c1 = b[0];
        c2 = b[1];
        S = b[2];
        c3 = b[3];
    }

@AlexK. Thank you! I looked for an answer, but got scared off by "javascript" answer. Didn't realize they were so similar. Is this the reason why someone voted my question down, do you think? — Chowzen, Sep 22 '16 at 13:39
Its a common question, the downvotes are probably because its expected that you show what you have already attempted. — Alex K., Sep 22 '16 at 13:40
@ThePerplexedOne how would one utilize your statement: "/([A-Z][a-z]+)/g"?? — Chowzen, Sep 22 '16 at 13:40
