Color Machine allows you to visualize colorspaces in 2D or 3D, and computes colorimetric values such as the color-rendering index or metameric index from spectra measured with the FD-7 device.


  • Colorspaces: XYZ, Yxy, Yuv, Yu'v', Luv, Lab, Lch, RGB, HSV, HSL, YCbCr.
  • Spectral data: Illumination and remission, requires data input. Currently, only the FD-7 measurement device is supported. Storing and loading of data is not possible (yet).
  • Observer: CIE 1931 2°, CIE 1964 10°, Judd 1951 2°, Judd Vos 1978 2°.
  • Illumination: Arbitrary blackbody, CIE A, B, C, D more...

  • Custom whitepoint now always has Y value 1.
  • Remission spectra are gray when a custom whitepoint is used.
  • Illumination spectra now show the background color relative to the more...


  • OS X 10.6.6 or later
