rgba errors in settings.json

[jcklpe]

I've got a bunch of Highlight settings I haven't touched in 4ish years and when I checked my setting file I saw they were throwing a bunch of errors:

 

example selection of one of my regexes:

// Self-closing HTML Tags
"(<(?!\\/p\\!))(.*|\n*|\r)(\\/>)": [
{
"borderWidth": "1px 0 1px 1px",
"borderStyle": "solid",
"borderColor": "rgba(192, 51, 57, .5)",
"borderRadius": "16px 0 0 0",
"backgroundColor": "rgba(26, 18, 26, 0.4)"
},
{
"borderWidth": "0 0 0 0",
"borderStyle": "solid",
"borderColor": "rgba(192, 51, 57, .6)",
"borderRadius": "0px",
"backgroundColor": "rgba(26, 18, 26, 0.4)"
},
{
"borderWidth": "1px 1px 1px 0px ",
"borderStyle": "solid",
"borderColor": "rgba(192, 51, 57, .5)",
"borderRadius": "0 8px 8px 0",
"backgroundColor": "rgba(33, 24, 28, 0.6)",
"color": "#c03339",
"fontStyle": "bold",
"fontWeight": "bold"
}
],

Any idea what I'm doing wrong here or why it's throwing complaints. Overall it seems to be working like normal.
