print colour and linking forms of different tables

When using the Print statement to produce details to a form (i.e. Print "Hello World"), how do you change the printed details (Hello World) colour to white, rather than black.

I'm also on a form which contains records about a horse (horse table), I want to use a button on this form which will open a form about horse scan records (scan table) and will open the scan record appropriate to the horse form record. The horse form contains the horse number and the scan from contians the horse number to link these together. I.e. horse form record where horse number = 10 to open scan form record where horse number = 10.
