The chromate ion (CrO4-2) has yellow colour so all the chromate compounds including silver chromate is yellow in colour.
Silver Chromate Ag=Silver CrO4= Chromate(a polyatomic ion)
No
In this reaction, the precipitate formed would be silver chromate due to the double displacement reaction between sodium chromate (Na2CrO4) and silver nitrate (AgNO3). Silver chromate is insoluble in water, so it will precipitate out of the solution as a solid, appearing as a yellow precipitate.

Silver chromate has a brown red colour
Silver Chromate Ag=Silver CrO4= Chromate(a polyatomic ion)
The chemical formula of silver chromate is Ag2CrO4.
Silver chromate is not soluble in water.
In silver chromate (Ag2CrO4), there are a total of 3 ions: 2 Ag+ ions and 1 CrO4^2- ion.
The yellow color of potassium chromate is due to the presence of the chromate ion (CrO4^2-). This ion absorbs light in the blue region of the spectrum, leading to the perception of a yellow color.
At the end point, so after all Cl- has reacted with Ag+, a brown-red precipitate of silver chromate (Ag2CrO4), is formed. (Argentometric indicator)Description:The solubility of silver chromate is slightly higher than that of silver chloride. So, in a mixture of both ions silver chloride will be formed. Only when no chloride is left silver chromate will be formed and precipitated out.Prior to the endpoint the solution has a milky lemon yellow appearance, due to the color of the chromate ion and the precipitate of silver chloride already formed.When approaching the endpoint, additions of silver nitrate lead to steadily slower disappearing red colorations. When the red brownish color remains (with grayish spots of silver chloride in it) the endpoint of titration is reached. (wikipedia)

The thermal decomposition of silver chromate results in the formation of silver chloride and silver chromite. Silver chloride is a white solid, while silver chromite is a brown powder.
The chemical formula for silver chromate is Ag2CrO4.
Ammonium chromate is a bright red to orange crystalline solid.
