Abstract: A device for determining tonal values of a graphic display comprises a mounting support which has a reference pin thereon and a positioning pin spaced away from the reference pin for example a radial line. A plurality of indicator members preferably in the form of wheels are provided and each of them includes a reference pin receiving opening to permit them to be rotatably mounted on a reference pin. In addition they include a plurality of circumferentially arranged defined images or word displays which have distinct characteristics in respect to tone or tint or color. The wheel is rotatable to present any one of defined areas with images or wording in a selected position for example an upright position for viewing. Each wheel also has a positioning pin engaging opening which may be engaged over a positioning pin defined on the support. This gives a selected orientation of one wheel and one or more additional wheels may be superimposed on the one wheel. The additional wheels are similarly oriented in order to provide a combined effect of tone, tint and color for ready viewing and appraisal.
