Or using PIVOT & UNPIVOT

SELECT  t.Date,
        unpvt.Name,
        unpvt.Color
FROM 
   (SELECT  Name, Colors, Color1, Color2, Color3
   FROM dbo.MYTABLE) p
UNPIVOT
   (Color FOR [Date] IN 
      (Colors, Color1, Color2, Color3)
)AS unpvt
Join dbo.MYTABLE t on t.[Name] = unpvt.[Name]
Where unpvt.Color != ''
