Abstract
One or more techniques and/or systems are disclosed for a colorant dispensing system that has a colorant dispensing head and a platform for holding a target canister into which colorant is dispensed. A light array can be used produce a light pattern in an arc of a circle at a height of an opening of the target canister. The light pattern can be focused at the opening of the target canister, to help a user align the opening with the dispensing head. The dispensing head is configured to dispense colorant within the boundary of the circle, such that the light pattern can act as a type of target for dispensing colorant into the opening of the canister to avoid issues when tinting. A control unit can be used with an interface to control the light array to accommodate different sized and shaped canisters.
