Adobe has updated its colour picker in the 2019 version. Especially in Adobe InDesign 2019, decimal places are now possible for LAB and CMYK during colour input, which is a long-desired feature especially in the high-end colour area. Up to now it was already possible in Adobe InDesign to enter colour values e.g. in CMYK with decimal places and to write them into the PDF during PDF export, but only integer values were displayed.
In Adobe InDesign 2019, three decimal places can now be entered for LAB and CMYK and can also be read out again. However, these values are not adopted in the automatic labelling of the colour fields, although this can always be adjusted manually.
Also in Adobe Illustrator 2019 CMYK inputs with decimal places are now possible, although only two decimal places are possible here. With LAB, only an integer entry is still possible.
Only Adobe Photoshop still does not allow any decimal places, but only whole numbers, it does not matter whether the file is in 8Bit or 16Bit. This applies equally to LAB, RGB, CMYK and grayscale: In none of the colour systems is a specification with decimal places allowed.
It is not really clear why only in some software solutions Adobe allows decimal places in colour definitions. But InDesign is clearly more important here than Photoshop and Illustrator; possibly because it is the last software in the production chain that has to merge data from different sources, and so the highest requirements apply here.
The import of ASE colour swatch data was not accelerated, the 2040 colour swatches of the freieFarbe e.V. CIELABHLC Colour Atlas take almost 2 minutes even on a current Macbook Pro. But the colour swatches are now displayed with full decimal values; a real improvement for the user who also needs high-precision colour data.
