create a realistic and beautifully rendered image of a modern industrial warehouse building on an overcast day the building should have light grey concrete walls with darker grey accents and metallic elements such as railings and stairs in cool steel tones the windows should appear as dark blue reflective glass add vibrant yellow safety bollards in front for contrast the sky should be overcast with soft diffused lighting to create a calm atmosphere the ground is paved with smooth grey asphalt slightly darker than the building walls with subtle shadows to add depth and realism
