There are procedures typically used in auto body shops to assist in matching a proposed paint mix with that on undamaged portions of the vehicle. A test panel is taped to a stick and arranged next to the panel to be matched at a couple of angles. The present procedures are unrepeatable and often utilize two individuals. According to embodiments of the present disclosure, a wand has a test panel portion with embedded magnets. The test panel is attracted to the test panel portion via the magnets and the wand holds onto the vehicle panel also via the magnets. The lower side of the test panel portion that sits against the vehicle has at least two flat surfaces at different angles so that the wand can be placed on the surface of the vehicle, or other surface, to assess the paint match from the different angles.

A colorimetric device and a colorimetric method according to the present invention extract a chart region candidate, which is a candidate for a chart region, from an image of a color chart, obtain an evaluation value of this chart region candidate, determine whether or not the chart region candidate is the chart region based on this obtained evaluation value, obtain each position of a plurality of patches for the chart region candidate determined as the chart region as a result of the determination and colorimetrically measure each of the patches at each obtained position of the plurality of the patches.

In a colorimetric device and a colorimetric method according to the present invention, chart definition information including at least patch position definition information representing each position of a plurality of patches in a color chart is stored, patch position measurement information representing the position of the patch is obtained on the basis of an image of the color chart, patch position correction information is obtained by correcting the patch position measurement information on the basis of the chart definition information, and then, each color of the plurality of patches is measured in each of the positions of the plurality of patches represented by the patch position correction information.

Systems and methods for color selection are provided. A user device displays room types on a display, receives a room type selection indicating a particular room type, displays types of feelings, and receives a type of feeling selection indicating a particular type of feeling. The user device accesses a lookup table that associates the room types and types of feelings with paint colors such that each possible combination of room type and type of feeling is associated with a subset of paint colors. The user device determines the associated subset of paint colors in the lookup table for the combination of the particular room type and the particular type of feeling and displays the associated subset of paint colors as recommended paint colors for the combination of the particular room type and the particular type of feeling on the display of the user device.
