Yes, you can. Just be aware that the index is case sensitive.

instead of

test.blue = 1

use

x = "blue"; text.x = 1

You can even do

blue = "blue"; test.blue = 1


Or in your new example you could initialise the index like this:

test. = 0
do i=1 to colour.0
   colour = colour.i
   test.colour = 1
end
