#Yes, #registering a design mark in black-and-white without a colour claim (“grayscale”) generally provides broader rights and more flexibility in usage. Without a colour claim, the trademark owner is free to use any colours or no colours at all to support the registration.

The absence of colour in a trademark registration provides would-be infringers with fewer arguments in defending against infringement. For example, those who use a confusingly similar logo would not be able to argue that they use different colours than those in the registration.
