View Patent ↗A tool including a frame that includes an aperture and a boundary marker disposed about the aperture. The boundary marker includes a first marker region disposed about the aperture and a second marker region disposed about the first marker region. The color of the first marker region is different from the color of the second marker region. The tool also includes a color correction scale disposed proximate to the aperture. The color correction scale has at least a first color correction region and a second color correction region. The color of the first and second color correction regions each have an LCh value of between L=73.5 C=15.3 h=55.6 and L=32.5 C=11.6 h=48.3.
1. A tool comprising:
a frame comprising an aperture;
a boundary marker disposed about the aperture, the boundary marker comprising a first marker region disposed about the aperture and a second marker region disposed about the first marker region, the color of the first marker region being different from the color of the second marker region; and
a color correction scale disposed proximate to the aperture, the color correction scale having at least a first color correction region and a second color correction region, the color of the first and second color correction regions each having an LCh value of between about L=73.5 C=25.3 h=60.4 and about L=32.5 C=11.6 h=48.3.
2. The tool according to claim 1 , further comprising a positioning device comprising a connector to attach the tool to a target substrate.
3. The tool according to claim 2 , wherein the positioning device comprises one of a hat, a handle, a pair of eyeglasses, or an adhesive strip.
4. The tool according to claim 1 , wherein the first and second color correction regions comprise different skin tones, each of the skin tones matching an actual skin tone at at least one lighting condition.
5. The tool according to claim 4 , wherein each of the skin tones match an actual skin tone at two lighting conditions.
6. The tool according to claim 5 , wherein each of the skin tones are a full spectral match for an actual skin tone.
7. The tool according to claim 4 , wherein the color correction scale comprises a third color correction region, the third color correction region comprising a skin tone different than the skin tone of the first color correction region and the skin tone of the second color correction region.
8. The tool according to claim 7 , wherein the color correction scale includes fourth and fifth color correction regions, the fourth and fifth color correction regions comprising a first grey tone and a second grey tone.
9. The tool according to claim 1 , wherein the aperture has a closed perimeter.
10. The tool according to claim 9 , wherein the first marker region comprises a ring disposed about the aperture.
11. The tool according to claim 10 , wherein the second marker region comprises a ring disposed concentrically about the first marker region.
12. The tool according to claim 11 , wherein the boundary marker comprises a third marker region disposed about the second marker region, the third marker region having a color different than the color of the first marker region and the color of the second marker region.
13. The tool according to claim 1 , further comprising an identifier attached to the frame.
14. The tool according to claim 1 , wherein at least two of the aperture, the boundary marker and color correction region are coplanar.
15. The tool according to claim 1 , wherein the first color correction region and the second color correction region comprise a square shape.
16. The tool according to claim 1 , wherein the color correction regions are silk screened to the frame.
17. The tool according to claim 1 , wherein the LCh value is determined using a 10-degree observer or a 2-degree observer.
18. The tool according to claim 1 , wherein the LCh value is determined using an illuminant selected from the group consisting of D65, A, F2, F7, F11, and TL84.
