In short, use the TICKTEXT property.

For example,

oAxis = OBJ_NEW('IDLgrAxis', /USE_TEXT_COLOR)
xobjview, oAxis ; default axis - all black

oAxis->GetProperty, TICKTEXT=oText ; Note that a single text object is
returned, containing a string for each tick.
oText->SetProperty, COLOR=[255,0,0]
xobjview, oAxis ; ticktext is now red

oFont = OBJ_NEW('IDLgrFont', SIZE=20)
oText->SetProperty, FONT=oFont
xobjview, oAxis ; tick text is now bigger
