It says it wants to see the colour value as a string. So in your case, you can use a CASE THEN ELSE END statement to get there.
CASE WHEN "Type" = 'SL' THEN '255,0,0,100' END There the numbers represent 'red,green,blue,alpha' Alpha is the transparency value. 0 is completely transparent and 100 is not transparent.
