Physical. Because its just in the appearance. Not chemical because than a new substance would form. Its physical for sure.
A blue color is typically a physical property since it relates to the appearance of a substance and can be easily observed without undergoing a chemical change. Chemical properties, on the other hand, describe how a substance interacts with other substances in terms of its chemical composition and reactivity.
The color of the sky being blue is a physical property, not a physical or chemical change. It is due to the scattering of sunlight by the Earth's atmosphere, particularly by air molecules and small particles in the atmosphere.
Dipping blue litmus paper in lemon juice is a chemical change. The acidic nature of lemon juice causes a chemical reaction with the blue litmus paper, turning it red. This change in color indicates a chemical transformation of the litmus paper due to the interaction with the acid in the lemon juice.
The blue color of copper II sulfate pentahydrate is a physical property, as it refers to an observable characteristic of the substance without changing its chemical composition. Chemical properties, on the other hand, describe how a substance reacts with other substances to form new products.
When aluminum foil is added to copper chloride solution, a chemical reaction occurs where the aluminum replaces the copper in the compound to form aluminum chloride and copper metal. This is a chemical change because the composition of the substances is altered. The physical change that occurs is the color change of the solution from blue to greenish-brown due to the formation of copper metal.
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.

A physical property.
indicators of a chemical reacton include color change, heat given off, and gas produced. indicators of a physical change are phase changes, changes in shape, and changes in size. "Being blue" is not a change at all. It's a condition.
chemical because you can not get the blue back
Dipping blue litmus paper in lemon juice is a chemical change. The acidic nature of lemon juice causes a chemical reaction with the blue litmus paper, turning it red. This change in color indicates a chemical transformation of the litmus paper due to the interaction with the acid in the lemon juice.
The change in color of a blue lobster turning red as it cooks is a physical change. The heat causes a structural change in the proteins within the lobster's shell, leading to the alteration in color. No new substances are being formed during this process.
It would be chemical.
The blue color of copper II sulfate pentahydrate is a physical property, as it refers to an observable characteristic of the substance without changing its chemical composition. Chemical properties, on the other hand, describe how a substance reacts with other substances to form new products.
