Color removed from entire application

[pikzilla]

Just a few moments ago, I was able to use the color black in my applications (That is, the darkest shade available). Now, however, when I select the color black from the color palette, I get instead a shade of very dark blue. When I adjust the RGB values to make the color truly black, the color I have selected suddenly becomes transparent. What's more, all instances of "true black" in my application have been replaced by this very unsatisfactory blue. How can I regain use of the color black, and hopefully replace all instances of the new blue with the black I used originally?

In the MMF2 animation editor, one color is used as "Transparent". This is not a special color unto itself- its just a single color in the RGB (0-255,0-255,0-255) color map. It is by default (0,0,0), the "true black" color, iirc. Any time you try to draw with (0,0,0), it will actually draw with (5,0,0)- a slightly reddish black. The transparent drawing color will be (0,0,0)
It is possible to set another color to be your transparent other than (0,0,0). If you do this, you can use pure black.

All you need to do is change the transparent color, just double click on the transparent square on the right side of the animation editor. It looks like a checkerboard setup (by default two aqua/teal shades, but you can change these too).

I get around this by setting a custom color of red=0 green=0 blue=1 Luminosity=0
So, 'technically', it's not true black, but the zero luminosity makes it look like a true black.

RGB and HSL are two different color models.
If any of the RGB values are >0, the luminosity MUST be >0 also.
