Fluid will probably be darker, and even if it's not, the lighter color might not be a true indicator of needing to be replaced. Workhorse for some reason doesn't make a specific recommendation (2006 Workhorse Chassis Manual), other than deferring to other manufacturers, who do recommend the brake fluid to be replaced every two years.
And since you have a model-year chassis that is susceptible to brake issues, it's best to stay on top of the brake maintenance.
