How can the order of storing values (RGB vs ARGB) impact the accuracy of conversions in PHP?

When storing values in RGB format, the alpha channel (transparency) is not included, which can impact the accuracy of conversions when transparency is needed. To solve this issue, values should be stored in ARGB format, where the alpha channel is included, allowing for more accurate conversions when transparency is required.

// Storing values in ARGB format for accurate conversions
$color = 0x80FF0000; // ARGB value with 50% transparency (80), red (FF), green (00), blue (00)
