Mobile paint system utilizing slider attribute prompts and reflectance memory storage

A method of producing a plurality of lines of user-selected paints from a plurality of prepaints en route to and/or at various locations, the method comprising:

• providing a mobile paint factory comprising:
• a vehicle;
• a paint production system located on the vehicle, the paint production system comprising, a plurality of aqueous prepaints, a plurality of supply reservoirs containing the plurality of aqueous prepaints, at least one receiving reservoir wherein the receiving reservoir receives at least two of the plurality of aqueous prepaints;
• a colorant system;
• a control coupled to the paint production system;
• a gloss meter which provides a gloss reading to the control;
• a spectrometer which provides a color reading to the control;
• and
• prompting the user to select, through the control, values for paint attributes, wherein the paint attribute prompt is a slider which allows the user to select the paint attribute from anywhere along a specified range;
• automatically dispensing through the paint production system predetermined amounts of appropriate prepaints into the receiving reservoir, wherein none of the prepaints are paints prior to being dispensed;
• and
• the paints having the selected values for paint attributes.
