--- Comment #15 from Christoph Schäfer <christoph-schae...@gmx.de> --- (In reply to V Stuart Foote from comment #1) > Spent some time in Scribus 1.5.2 and downloaded and installed the OCSC CIE > HLC palette (via Windows -> Resources -> Palettes category). Not so sure > this should be a palette to adopt as a replacement LibreOffice standard.soc > in whole. > > Yes it has application for reproducible color management for desktop > publishing support, but the HLC colors are rather muted--and the palette > lacks handling of the primary colors. Folks will find it too muted and not > the best sRGB color space coverage. > > Still it would be a useful palette to bundle, and perhaps provide some > mechanism for import of the OCSC libary of palettes to LibreOffice. > > Some technical issues on using the CIE HLC in LibreOffice. > > As noted, would need to resolve how to label each color swatch to show in > its tool-tip popup. Any freieFarbe / freeColour naming in Deutsch would have > to be translated--or maybe better drop any color names and depend on the > swatch viewer alone (similar is done now for a few of the palettes--where > for some reason naming for cmyk uses CMY, and gallery uses CMYK) -- but > which sRGB (decimal or HEX) or CMYK (decimal)? > > And, if moving forward with an HLC based model, it is appropriate/necessary > to rethink grid layout for the swatch display. > > Currently we use 12 columns--chosen to hold black, white and our 10 > increments of gray1 - gray10. Something like the HLC tables organized by Hue > 000 -> 360 into 36 tables, would need to go into a 9 column layout, with > divider between the Hues--and the table would need to describe swatch blanks > for colors outside the sRGB color space. > > Download Owen G.'s tonal_row.soc (attachment 105128 [details] from bug > 80196) to $ORIGIN/share/palette and you can see challenge of the swatch view > being fixed number of columns. > > Also, since each swatch from a palette will be shown on opening the color > picker, the color picker widget currently has no support for an HLC CIE LAB > color reference. Rather, like Scribus, we provide only an HSV (i.e. our HSB > panel) based color cylinder representation drawn from sRGB values in the > .soc palette. Can conversions showing HLC field be added? > > > =-ref-= > https://en.wikipedia.org/wiki/HSL_and_HSV > > https://en.wikipedia.org/wiki/HCL_color_space > > http://cscheid.github.io/lux/demos/hcl/hcl.html The HLC colours are "muted" for a reason: They can be replicated in CMYK, so if you are working in a cross-media workflow (web and print) and need a maximum of colour correctnes without resorting to spot colours, this is what you want. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ Libreoffice-ux-advise mailing list Libreoffice-ux-advise@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-ux-advise
