rgba2550005

The term rgba2550005 refers to a compact, nonstandard encoding used in some software to represent a color by concatenating the decimal values of its red, green, blue, and alpha channels into a single string prefixed by 'rgba'. In this representation, the values are 255 for red, 0 for green, 0 for blue, and 5 for alpha.

Because alpha is handled differently across systems, the meaning of '5' is ambiguous. In common RGBA models, alpha is either a normalized floating point [0,1] or an 8-bit integer [0,255]. If the '5' is on a 0-255 scale, it corresponds to approximately 0.0196, implying high transparency. If the scale is 0-1, '5' would be invalid; if the last digit is a separate precision indicator, other interpretations apply. Without documentation, the value cannot be reliably interpreted.

Origins and usage: Such tokens often appear in design tool exports, shader parameter dumps, or serialized color data where readability is sacrificed for compactness. They are not part of the standard CSS color syntax or widely used image formats.

Practical guidance: when encountering rgba2550005, identify the source format or schema, confirm the intended alpha range, and convert to a standard RGBA representation (for example, rgba(255,0,0,0.5) or rgba(255,0,0,255)) as appropriate to the target system.
