NotMyFault Posted February 12, 2021 Share Posted February 12, 2021 I might be wrong or expecting to much. When using a document with 16 or 32 bit color depth, and 16-bit colors in color panel, i would expect beeing able to enter 16-bit values to RGBHEX. But it will only accept 00-FF (8 bit) and always replace the "high" byte with 00. The "resulting" color code from all 3 channels will simply double/repeat the given 8-bit hex value. This is at least confusing, or a bug. HSL or LAB do not offer any option to enter 16-bit values. And last but not least, the info panel is completely unable to show 16-bit colors. All you get is either 8-bit or less than 7-bit if using % (0-100%). Only option to enter 16-bit is using RGB or greyscale. Only option to display 16-bit color value is to use color picker, and read out result in color panel.

NotMyFault Posted February 20, 2021 Author Share Posted February 20, 2021 This video explains why the color panel is broken with respect to showing 16 bit colors in RGB hex mode (16 bit). The hex code with 4 digits for every color channel should show values from 0000 to FFFF. Instead, it shows 0000 to 00FF. Consequently, the values are truncated to 8 bit / 256 values. Only the combined field (below the 3 color channels, starting with #) will show the correct 16 bit hex value of all 3 channels 2021-02-20_18-14-48.mkv Quote Mac mini M1 A2348 | Windows 10 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

Old Bruce Posted February 20, 2021 Share Posted February 20, 2021 Use your Hamburger menu in the upper right to choose 16 bit.

NotMyFault Posted February 20, 2021 Author Share Posted February 20, 2021 Hi Old Bruce, your comment does not help, as16 bit is active, of course. Otherwise you would see only 2 digit hex codes. This bug may affect Windows OS only, explaining that you may not see it on your Mac devices. 8 bit: 16 bit: Quote Mac mini M1 A2348 | Windows 10 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

Staff Gabe Posted February 23, 2021 Staff Share Posted February 23, 2021 Hi both, Sorry for the delayed reply. @Old Bruce This only seems to be a Windows issue, so you would not have seen it. Now logged. Quote Link to comment Share on other sites More sharing options...
