[Solved] TikZ: Get colour from an array and use it for drawing

optimal benis Asks: TikZ: Get colour from an array and use it for drawing
Using the arrayjob package, I am able to extract strings from an array and, for example, get TikZ to print that text:

Code:
documentclass{standalone}
usepackage{tikz}
usepackage{arrayjob}
newarraycolours
readarray{colours}{red&orange&yellow&green&blue&purple}

begin{document}
    begin{tikzpicture}
        foreach i in {1,2,5} {
            draw (0,i) node{colours(i)};
        }
    end{tikzpicture}
end{document}


enter image description here

However, I want to colour lines with variable colours in the same way. Naively, I try the following code, which does not work:

Code:
documentclass{standalone}
usepackage{tikz}
usepackage{arrayjob}
newarraycolours
readarray{colours}{red&orange&yellow&green&blue&purple}

begin{document}
    begin{tikzpicture}
        foreach i in {1,2,5} {
            draw[colours(i)] (0,i)--++(1,0);
        }
    end{tikzpicture}
end{document}

This is a toy example to illustrate what I want. There are obvious ways to do this in this small example, but not my application. I want to extract the colour from an array by index and use that colour to colour the lines.
