I am trying to create a coloured transparant button with 4 variables (sliders). Standard solution: set background color, make color, make list, 4 parameters RGB & Alpha). With this button I have to simulate the color of RGBW leds. With a white background behind the button and a variable transparency I can simulate the white part of the RGBW led. The 4th variable in the list is the alpha parameter. RGB sliders are working fine but the alpha slider 'fades' to black.
I have tried every possible background color combination ( screen, arrangement, component background - none, white) also uploaded a white background-image into the screen. The button keeps 'fading' to black and I need to 'fade' it to transparent white (white background)
Am I doing something wrong ?
Can someone help me and explain ?
