Custom grid colour

PaulWilliams

In Oasis Montaj viewer 9.3 I have a grid containing position coordinates (x,y) and magnetometer altitude (z). I would like to change the grid colour so that everything under 3.5m is blue and everything over 3.5m is red. How can I do this? I've tried using the colour tool but it only seems to want to change colour according to distribution. I'd appreciate any help with this.

Thanks for the the file and instructions which are very helpful although when I tried to create my own I don't see that Linear Transform box within the Colour Tool when I select Linear Distribution.
