I am uploading a patch with above stated solution.

amritsingh09 → created an issue.

I have removed

  '#attributes' => [
      'id' => 'field_select_colour',
    ],

from radio button as assigning it the attribute id will break the radio button, making it inaccessible.

In first example i have explained the same as well in comment.

Also in all radio buttons example i have replaced 

  ':input[id="field_select_colour"]'

to

':input[name="colour_select"]'
