How can I change colors of grease pencil strokes drawn in 'vertex color' paint mode? If I have drawn grease pencil line strokes in 'material' paint mode, I can easily change colors of them by using base color button(marked with a white arrow in above picture).
But after I had drawn some line strokes in 'vertex color' paint mode by a way of trial, I realized that I don't know how to change colors of them.
Help me.
Change from Draw mode to Vertex Paint mode (top-left of the screen) and you'll be able to change the strokes colour.
But you won't be able to just change the colour of all strokes at once, like when using a material then editing it. You'll have to manually re-paint over each stroke with the new colour.
