color picker default color(255) with colorMode(HSB, 1, 1, 1, 1)

[KrabCode]

when the user has colorMode(HSB(1,1,1,1)) on the main user canvas, the default color(255) gives him zero alpha in an otherwise normal looking color picker

this might be an easily detectable cause of some common confusion, maybe we can tolerate this error and we could still return a full alpha picker by default
