Starting with changing text color in day field of Diarium (before inserting any text - so not selecting anything, just changing color)
Then inserting any text form clipboard - the text is inserted in selected color.
Selecting a part of the inserted text - and choosing another text color (from text color icon - and so on) - first time one picks the color it is as 'automated' (no color). Selection stays - and then if you choose the color second time - the choosen color is set and text is in this color.
So first time you press text color button (any) it clears text color, and second press sets the text into choosen color
