   `ColorConverter.parseToStringColor` already rejects color components above 
255, but the `JAVA_COLOR_PATTERN` label prefix `[A-Za-z\d._]+` includes `\d`, 
so for a bare triple whose first component has four or more digits the greedy 
label swallows the leading digit and the first capture group only sees the 
trailing one to three digits. `1234,5,6` is parsed as `Color(4,5,6)`, and 
`1000,0,0` / `2550,0,0` as black, so a malformed out-of-range value is accepted 
as a different in-range color instead of ever reaching the `> 255` check. 
Binding the optional class-name label to its opening `[` 
(`(?:[A-Za-z\d._]*\[)?`) stops it absorbing digits from the numeric groups; 
every string `Color#toString()` emits still parses the same, including class 
names that contain digits. Found while auditing the converters that parse 
untrusted strings.
