Queen Letizia, 47, chose a soft pink outfit as her and husband King Felipe, 50, welcomed Mexican President Enrique Pena Nieto and his wife Angelica Rivera Hurtado to the Zarzuela Palace, Madrid.
Letizia chose a baby pink coat which featured a delicate multicoloured floral print.
The coat had a small collar and six green buttons, which she wore closed.
Keeping the look tonal, Letiiza opted for matching blush pink court shoes.
In her hands, Letizia held a green snakeskin clutch bag which picked up on the colours in her coat.
Letizia wore a pair of vibrant green and pink drop earrings in her ears to tie the look together.
Angelica, meanwhile, chose a vibrant red and white outfit which was possibly a nod to Spain – red is often associated with the country.
She chose a red pussybow blouse and white pencil skirt with a sheer panel on the top which gave a flash of leg.
The Mexican President’s wife finished her outfit with a pair of snakeskin court shoes.
Both women made sure their hair was freshly blowdried, and their makeup was impeccable.
Earlier this week, Queen Letizia attended an awards ceremony in Madrid with her husband and again chose pink.
Looking her best, Letizia chose a simple pink shift dress. A matching pink summer coat was worn over the top.
The summer coat nipped in at the waist, and featured a embellished floral pattern on the edges.
Keeping to the colour scheme, Letizia held a blush pink clutch bag in her hand.
Simple nude stiletto court shoes completed the look, and Letizia chose not to wear tights.
Last week, Letizia and her husband looked every inch the power couple in their attire, continuing with their united front after embarrassing footage of an incident between Letizia of Queen Sofia, her mother-in-law, went viral.
Letizia looked elegant in a simple blue dress with matching summer coat.
The mum-of-two’s coat was nipped in at the waist, and featured heavily detailed lace arms, her skin flashing through underneath.
The lace pattern continued on the sides of the coat, which closed with seven small buttons at the middle.
Continuing the muted colour scheme, Letizia carried a small grey clutch in one hand.
