Acredito que não seja possível mudar a cor da fonte de um commandbutton, vc tem que escolher outro tipo de botão.
Para mudar de botão: menu Project/Components../Guia Controls/selecione a opção Microsoft Forms 2.0 Library/e clique em aplicar.
Irá aparecer vários outros objetos escolha o Command Button e altere suas propriedades....

Não tenho certeza... Mas acho que não é possível.

[ô] This module provides an easy way to change the text color
[ô] of a VB CommandButton control. To use the code with a
[ô] CommandButton, you should:
[ô]
[ô] - Set the button[ô]s Style property to [Ô]Graphical[Ô] at design time.
[ô]
[ô] - Optionally set its BackColor and Picture properties.
[ô]
[ô] SetButtonForeColor Command1, vbBlue, Alignment
[ô]
[ô] - Call UnsetButtonForeColor in the Form_Unload event:
[ô] UnsetButtonForeColor Command1
