You use universal indicator or litmas paper and then judging by the colour it goes you can find out the pH
This might not be your answer, but universal indicators change colour when they come in contact with a substance. It will then change to the colour of its corresponding pH. So, in terms of bases, it turns from a turquoise (from green which is pH7) to a dark purple the more alkaline it is(<7-14) and in terms of acids, it goes from a green-yellow to a dark red (>7-0).
With a pH of 12 it is very alkaline and would turn universal indicator dark blue.
Black is universal. Anything goes with black, white, prints, pastels, brights, it all depends on what you feel comfortable wearing.
it goes colourless in an alkiline soloution but in an acidic substance it goes a fushia pink colour! You are WRONG! The solution will be colourless at acidic and neutral pH and goes pink above about pH 8, I hope you aren't a science teacher.

It goes purple
it goes bluey purpley when it is in water and red in acid and yellow - green in alkali
The universal indicator goes bright red. I thought it was dark red lol =D i joke! i knew it was bright red. that's what mr. bayes, my science teacher said. he used to be a scientist
Yes it does. In some flowers, they act like Universal Indicator. (universal indicator goes blue if its very basic- also known as alkaline- and it goes red if something is acidic) So some flowers go red in acidic soil, and change to blue if the soil goes basic.
you mix them up and see what colour it goes
Litmus paper goes red or blue in acids or universal indicator may measure some level of pH

universal indicator goes from yellow to dark red when put in an acid. there are many other indicators that all go different colours
If it goes red, that means it is an acid, and based on the strength of the colour the higher the acidity level. For example, an orange is not as strong as a red.
The bubble bath has a dye added to it called Bromocresol Green which is a pH indicator, it will change colour as you change the pH of the bathwater - how acid or alkali the solution is. (Interestingly the one colour it never goes is green!)So as you dilute the bubble bath, which starts off slightly acid, the pH then gets higher and the water becomes more alkaline, making the Bromocresol Green change from orange to blue. If the water becomes acid again it will change from blue back to orange.
