  • 2010-08-05T05:28:26Z Gringer 605x115 (17964 Bytes) 10-step iterative chroma smoothing, slightly brighter grey point
  • 2010-08-04T15:34:49Z Gringer 605x115 (17964 Bytes) Smoothing applied to largest reduction in saturation (blue to cyan)
  • 2010-08-04T14:40:43Z Gringer 605x115 (18828 Bytes) Only using one adaptation matrix, finer resolution at blue clip point
  • 2010-08-03T13:12:09Z Gringer 605x115 (18828 Bytes) using Chroma-based cartesian coordinates for search
  • 2010-08-03T12:44:16Z Gringer 605x115 (18828 Bytes) Modified MH matrix slightly based on [http://www3.interscience.wiley.com/journal/112396194/abstract this]
  • 2010-08-03T11:51:18Z Gringer 605x115 (18828 Bytes) whoops, that was an older version
  • 2010-08-03T11:43:39Z Gringer 605x115 (13629 Bytes) slightly different MCAT02 matrix, different binary search algorithm
  • 2010-07-31T16:06:13Z Gringer 605x115 (17964 Bytes) using CIECAM02 model
  • 2010-07-29T11:00:29Z Gringer 605x115 (17964 Bytes) adjusting intensity between linear sRGB and non-linear sRGB, as gamma correction is encoded into that transform.
  • 2010-07-29T08:51:03Z Gringer 605x115 (17965 Bytes) Trying a gamma correction of 2.2 (e.g. x^(1/2.2)), rather than square root function
  • 2010-07-28T11:35:33Z Gringer 605x115 (17964 Bytes) generated RGB equivalent spectrum using sRGB matrix transform + spectrum->XY lookup tables.
  • 2008-11-17T04:40:12Z Gringer 605x115 (13629 Bytes) Added cyan band again, reduced luminosity to try to fit colour with [[:Image:NASA_Hydrogen_spectrum.jpg]].
  • 2008-08-31T01:53:18Z Gringer 605x115 (13488 Bytes) Updated using "Electric violet" colour @ 400nm, Luminosity reduced to remove Mach bands
  • 2008-08-30T02:18:35Z Gringer 605x115 (13487 Bytes) Attempt assuming monitor RGB are the same as monochromatic wavelengths from http://www.cis.rit.edu/mcsl/research/broadbent/CIE1931_RGB.xls, used wavelengths from there for transition points (except for violet, which was left
  • 2008-08-29T11:59:06Z Gringer 605x115 (13503 Bytes) Attempt using RGB colours from http://hyperphysics.phy-astr.gsu.edu/hbase/vision/cie.html#c4
  • 2008-08-29T04:01:38Z Gringer 605x115 (13614 Bytes) Added cyan point at 495nm, reduced luminosity of most colours in an attempt to remove [[w:Mach bands]]
  • 2008-08-28T04:47:24Z Gringer 605x115 (13488 Bytes) Changed violet RGB representation to "colour wheel violet"
  • 2008-08-28T04:30:23Z Gringer 605x115 (13488 Bytes) Forgot to re-align wavelength bands to start of rectangle
  • 2008-08-28T04:25:36Z Gringer 605x115 (13488 Bytes) Reverted to old colours (with metadata), added wavelengths at transition points (to make more like [[:Image:Logarithmic visible spectrum.svg]]
  • 2008-08-28T03:01:06Z Gringer 600x70 (1989 Bytes) Removed metadata in SVG to reduce file size.
  • 2008-08-28T02:52:18Z Gringer 600x70 (5007 Bytes) Reduced luminosity for colours to make transition less jarring [[Category:spectrum]]
