RGB إلى HEXA
Opaque by default
Converting plain RGB to HEXA usually appends FF alpha (fully opaque), producing #RRGGBBAA. This is handy when your design system standardizes on eight-digit hex even for non-transparent swatches.
When not to use
If you need partial opacity, start with RGB إلى RGBA (set alpha) before serializing. Otherwise teammates may assume translucency is already encoded when it is not.
