A strongly basic solution with Yamada's universal indicator will depict an Indigo or violet  color

Yamada's universal indicator, patented in 1933, by Yamada  is a pH indicator produced by combining  several compounds ( water, 1-Propanol, phenolphthalein, sodium hydroxide, methyl red, bromothymol blue, Sodium bisulfite, and thymol blue) to estimate acidity and alkalinity of solutions by  indicating a  clear  color change over a wide range of pH values.

Because of the ease in transition of colors from acidity to alkalinity, Many other variations of universal indicators have been produced. Experimenting  with Yamada's universal indicator as  described in the Journal of Chemical Education,explains that the pH of a solution, after adding the  universal indicator, are as follows

  • pH range  < 3 will depict  a red color to indicate presence of a strong acid.
  • pH range    3–6 will depict a Orange or Yellow color to indicate the presence of a weak acid.
  • pH range 7   will depict a Green color to indicate the presence Neutral solution.
  • pH range 8–11 will depict a blue colour to indicate the presence of a weak alkali.
  • pH range > 11 will depict  an Indigo or violet  color to indicate the presence of a   Strong alkali .

Note that alkali solution is same as  basic solution.
