Welcome to the shade varieties of the KGVI-reign. Which catalogue are you using?

The $1 Johore is listed in three colours in the King George VI Commonwealth Catalogue. Shades, really, for different printings. Here they are:

1. ultramarine & deep red-purple
2. blue and red-purple
3. pale blue and purple.

I suggest that yours is no. 3, but you must get several copies together and put them under a broad-spectrum light, and compare them. Keep in mind that used stamps that have been soaked off, in water, and exposure to light can change the colours... so it is not an exact science.
