*=yellow, not too light but not too dark
-=I did six different shades, going from darkish yellow at the top down to a nice dark red.
.=a lightish yet robust blue- like TARDIS blue with water in.
Other than that, backstitch the word 'DOCTOR' inside the red banner in white. I also backstitched around the letters in WHO (also in white) because the letters tend to run together.
