'Schreiend' (screaming) is the present participle of the verb 'schreien' (to scream). This form is used as an adjective to describe a quality that occurs at the same time as the action of the verb.
Die schreienden Fans feierten den Sieg ihrer Mannschaft.
The screaming fans celebrated their team's victory.
You can recognize the meaning of 'schreiend' (screaming/glaring) from the noun: If it refers to a living being, the literal meaning is intended. If it refers to a color, it means 'grell' (glaring/bright). If it refers to an abstract noun like 'Ungerechtigkeit' (injustice), it means 'obvious and outrageous'.
Ein schreiender Papagei saß auf dem Baum.
A screaming parrot was sitting in the tree.
In the meaning 'grell' (glaring/bright), 'schreiend' is combined directly with color names. Typical examples are 'schreiendes Rot' (glaring red), 'schreiendes Grün' (glaring green), or 'schreiendes Gelb' (glaring yellow).
Die Wände waren in einem schreienden Gelb gestrichen.
The walls were painted in a glaring yellow.
In the figurative meaning, 'schreiend' is combined with negative, abstract nouns. Common combinations are 'eine schreiende Ungerechtigkeit' (a glaring injustice), 'schreiendes Unrecht' (glaring injustice/wrong), or 'ein schreiender Widerspruch' (a glaring contradiction).
Es ist ein schreiender Widerspruch, Wasser zu predigen und Wein zu trinken.
It is a glaring contradiction to preach water and drink wine.
loud / according to
'laut' and 'schreiend' can both have to do with high volume. 'laut' is general and neutral: music, voices, devices, or traffic can be 'laut'. 'schreiend' is narrower. It describes someone or something that is screaming or sounds like a scream, often out of fear, pain, or anger. That is why 'schreiend' sounds stronger and more emotional than 'laut'. If you only mean the volume, 'laut' usually fits. If an actual scream is meant, 'schreiend' is more precise.

Das schreiende Kind wurde nach dem Sturz sofort von seiner Mutter getröstet.
The screaming child was immediately comforted by his mother after the fall.
