Answer 1

You should actually fix your database schema so that you have three tables:

shirt: shirt_id, shirt_name
color: color_id, color_name
shirtcolor: shirt_id, color_id

Then if you want to find all of the shirts that are red, you'd do a query like:

SELECT *
FROM shirt, color
WHERE color.color_name = 'red'
  AND shirt.shirt_id = shirtcolor.shirt_id
  AND color.color_id = shirtcolor.color_id
