Thanks for your answer. However, it does address my question, I am afraid.
I have well understood how to change the color of the button, with a # value also. My problem is when I do this (“my” color is #e84e0f, in this case) the TEXT color inside the button also changes, which renders it very hard to read (it is also an orange, like the button color). Basically, I would like the text font to remain white, in this case, to make the text easily readable inside the button.
This is why I was asking for a second code to manage manually the button text color, on top of the button color itself.
Thank you. Best regards.
