So I created the text with the add text button - I'm using version 2.91 - then I went to the right tab with all the properties functions: world properties, materials properties, physics properties, etc., then I extruded the text a bit(stretched it).
Next, I went to the materials tab to color it, clicked on new , the sphere showed up, then I clicked on the color line(base color) and chose a color, but nothing happened to the text.
