Litmus paper will likely turn blue when applied to washing detergent due to the alkaline nature of most detergents. This color change indicates that the detergent is basic.
As soap is alkaline in nature, it turns red litmus paper blue
When red litmus paper is placed in washing up liquid, it typically changes to blue. This color change occurs because washing up liquid is usually alkaline (basic), and red litmus turns blue in the presence of a base. Thus, the transition indicates the basic nature of the washing up liquid.
If litmus paper is added to washing up powder, it would typically turn blue, indicating that the washing up powder is alkaline (basic). Most washing up powders contain sodium carbonate or other alkaline substances, which raise the pH and cause the blue color change in blue litmus paper. If red litmus paper is used, it would remain red, confirming the basic nature of the solution.
Blue litmus does not change when placed in a basic solution.
Washing soda is originally white in colour and no colour change takes place on heating it. A colourless gas, water vapour i.e the water of crystallization is evolved which is neutral to litmus and even turns cobalt chloride blue to pink. The left residue is sodium carbonate (white).

Adding washing powder to litmus will not have a noticeable effect on the litmus itself. Litmus is typically used as an indicator to determine acidity or alkalinity by changing color when exposed to different pH levels. Washing powder is a detergent and typically does not interact with litmus in a way that alters its color or properties.
The blue litmus paper will not change color. Red litmus would turn blue in the presence of ammonia. Blue litmus paper will only change color in the presence of an acid, at which point it will turn red.
If liquid detergent turns red litmus paper blue, it is likely a base. Red litmus paper turns blue in the presence of a base, indicating that the detergent is causing a basic reaction.
detergent solution has an effect on red litmus paper because detergent solution is a base and it changes the color of red litmus(indicator) to blue when in contact with it.

Washing detergent is nearly always alkaline or antacid. There are some special purpose soaps - called soapless soaps, that are mildly acidic, but they are for special purposes and not usually encountered. On the other hand, detergents with ammonia in them are strongly alkaline.
