Description: Is is not (intuitivly) possible to mark a binary operator in a formula with a color. The use case is to display a = b + c with a red "+" sign. Steps to Reproduce: 1. create a new libre office document (I normally use Impress). 2. create a formula object in this document 3. use the following formula code for example: a =b color red {+} c Actual Results: The display shows: a = b + ?c? The characters starting from the + sign are in red color. Expected Results: The display should show: a = b + c My expextation was that the "plus" sign only gets the red color. Reproducible: Always User Profile Reset: No Additional Info: Version: 7.0.0.0.alpha0+ Build ID: 7fddb9a1f69a1bac676ad48421256a1ba0274c83 CPU threads: 4; OS: Linux 4.15; UI render: default; VCL: gtk3; TinderBox: Linux-rpm_deb-x86_64@86-TDF, Branch:master, Time: 2020-02-16_19:33:19 Locale: de-DE (de_DE.UTF-8); UI-Language: en-US Calc: threaded
To apply to the operator, you have to apply a color to each element of the formula. size 20 { color green a color red + color green b = c} or color black a^2 color red + color black b^2 = color green c^ color red 2 Glyph for a 'relation' or 'set operator' can not be colored individually, but will take a color applied to the whole formula. Colors available to work with are: black, white, red, green, blue, cyan, magenta, yellow, teal, silver, gray, maroon, purple, lime, olive, navy, and fuchsia No support yet of MathML hex-tupple RGB custom colors (see bug 40436)
