I made a keyboard (I call it the colorboard) that you can use to make colors! it even displays their HSVA! Now I know what you're probably thinking, what does HSVA mean? How do I use this keyboard?

1-
H is for Hue, or color
S is for saturation, or lightness
V is for Value, or darkness
and A is for Alpha, or transparency
2- You use the colorboard by clicking the buttons, the last person that used it left those sticky notes on it. I don't really know why.
Have fun using the colorboard!
