Hello. Currently in LibreOffice, we have options to select the shadow colour of drawing objects. However for text (whether in the main body or in text boxes) it is only possible to switch shadow on and off and the shadow is displayed in a a compulsory blackish colour. This is not always pleasant on the eyes especially when non-black colour foreground text colour is used. Therefore I sincerely request to provide an option to specify the colour of text shadow.
Confirmed. Like inability to change the fixed fill color of the "Outline" effect, the "Shadow" font effect remains black even if a font color has been assigned. Not a dupe, but implementing framework (and extending ODF to describe) font effect for "Outline" color of see also bug 99400 (and dupes) would probably support assignment color to the Shadow font effect. Enhancements should be tracked together.
The text shadow is described by the fo:text-shadow attribute. The specification refers to XSL, and that refers to CSS. So in fact ODF uses https://developer.mozilla.org/en-US/docs/Web/CSS/text-shadow A change or addition in ODF is not needed. The current specification already allows to set a shadow color. LibreOffice 'only' needs to implement it.
