5.9.1 problem with changing text colour

Hi!
I have been used to changing the colour of text, headings and buttons by simply typing in the colour code; 043D06. This works on some things (advanced lists) but not on others (buttons, plain text, headings). I assume this is a glitch?
The option to change colour is there, so is the colour wheel and what seems to be a typing box but there is no way of typing in the required code. The only way to change colour is to hover over the colour wheel – it is impossible to pick the precise colour needed in this way.
